You can solve any algebraic eqution using this easy method. First you should add 7 in this case because your trying to isolate x. Then divide the sum by 7 and you will find what is x. Try it and figure out the answer. I hope this helped.

BEDMAS in reverse

First deal with additions and subtractions: 7X-7+7=56+7-->7X=63

 Then deal with multiplications

Quick solution.....add 7 to both sides....then, divide both sides by 7....ask us if you get "lost"
