First to solve your problem you need to ask yourself what is happening to the variable.
For example x-7=56.
Second you do the inverse operation (opposite) to each side of the problem.
x-7=56
+7 +7
Last you re-write the variable
x=63
Now here are the steps to check your answer:
1.Re-write ex. x-7=56
2.Plug in your answer ex. 63-7=56
3.Simplify ex. 56=56
4.Variable exquals answer ex. x=63

Good job explaining how to solve equations. It would have been nice if you would have defined variable and equation, added a link, and/or found a real life application of equations.
