How can you check the solution of an equation?

Look at the left hand side of equation and if given number matches

do the same for the right hand

see if numbers match

In order to check you would plug in the value of x and see if it equals the same thing.

or do the opposite of the equation. it depends on if you are dealing with x or not. so if you have 6-3 is 3 you can do 3+3 is 6
