## Equation is a math sentence that says that 2 things are equal.
An equation always has an equal (equation_{=}) sign. The thing or things that are on the
left side of the equal sign are equal to the things on the right side of the
equal sign. Here are a few equations:
In the first equation, if Y is 2, then X must be 2 + 5 or 7 to make the equation true.
In the second equation, if B is 10, then A must be 6 to make the equation true.
In the third equation, the number next to the letter means multiply the value of the
variable represented by "A" by 3. So if A is 4, then Z must be 12 to make the third
equation true. To learn more about solving equations, see how to solve an equation. Now here's a problem for you: In the first equation, if Y were 10, what would X be? |
