Hello, math friends! Welcome to our fun math adventure. Today, we’re going to learn about equations and how to solve them step by step. Let’s dive in!
An equation is like a math sentence that shows two things are equal. It has two parts: one on the left and one on the right, with an equal sign (=) in the middle. This means both sides have the same value. For example, in the equation 2 + 5 = 7, both sides equal 7.
In equations, we have constants and variables. Constants are numbers that stay the same, like 2 or 5. Variables are like mystery numbers we need to find, usually shown as letters like x. When we solve an equation, we’re finding the value of the variable.
To find the value of x, we use math operations like addition and subtraction. Let’s learn how to solve equations using these operations.
Imagine we have an equation: x + 3 = 9. Our goal is to find out what x is. We do this by getting x alone on one side of the equation. Right now, x is with +3. To move +3 to the other side, we do the opposite operation, which is subtraction. So, we subtract 3 from both sides:
x + 3 – 3 = 9 – 3
This simplifies to:
x = 6
Great! We found that x equals 6. To make sure we’re correct, we can check by putting 6 back into the original equation: 6 + 3 = 9. Both sides are equal, so we did it right!
Let’s try another one: x – 4 = 8. We need to get x by itself. This time, we do the opposite of subtraction, which is addition. We add 4 to both sides:
x – 4 + 4 = 8 + 4
This simplifies to:
x = 12
Awesome! We found that x equals 12. Let’s check our work by putting 12 back into the original equation: 12 – 4 = 8. Both sides match, so we got it right again!
Now you know what an equation is and how to solve it using addition and subtraction. It’s a super useful skill to have. Keep practicing, and you’ll become a math whiz in no time!

Hello, math friends! Welcome back to my channel. Today, we are learning about equations and how to solve them. Let’s take it one step at a time.
What is an equation? An equation is a mathematical statement that shows that two expressions are equal. There is one expression on the left and one on the right, with an equal sign in the middle. The two equal expressions have the same value; that is why there’s an equal sign. For example, 2 + 5 = 7.
In an equation, we have constants and variables. Constants are numbers with a fixed value; they don’t change. Variables are the unknowns, usually represented by letters, with the most common one being x. When we say that we are going to solve an equation, we mean that we are going to find the value of the variable, which is the value of x.
To find the value of x, we use mathematical operations like addition, subtraction, multiplication, or division. Today, we’re going to learn how to solve equations with addition and subtraction.
Let’s solve this equation. As we said before, the main goal of solving an equation is to find the value of x. We do this by isolating it on one side of the equal sign, with everything else on the other side. When we move parts of an equation from one side to the other, we have to keep the equation balanced, so be careful.
In this equation, we’re going to isolate x on the left side. Right now, x is accompanied by an operation, +3, so we need to move that to the right side and isolate x. We do this with the reverse operation of addition, which is subtraction. To keep the equation balanced, we subtract 3 from each side of the equation: 3 – 3 = 0 and 9 – 3 = 6. Look, now we’ve isolated x, so x = 6.
Equation solved! Remember to check your work to see if we solved for x correctly. We can plug the result into the initial equation. Let’s try it now: both sides of the equation have the same value, since 6 + 3 = 9. Now we know our work is correct!
Shall we try another one? Remember that we have to isolate x on one side of the equation. We start with the reverse operation of subtraction, which is addition. We add 4 to each side of the equation to keep it balanced: -4 + 4 = 0 and 8 + 4 = 12. So, x = 12.
To check our work, let’s plug 12 into the original equation x – 4 = 8. 12 – 4 = 8. Fantastic! 8 = 8. We did it!
Now we know what an equation is and how to solve it. It’s an important skill. See you soon, friends!
