Let's solve this equation and put the words with it along the way.

1) 7x = 2(x - 5) [given: this is, well, the problem]

2) 7x = 2x - 10 [Distributive Property: 2 was distributed throughout (x-5)]

3) 5x = -10 [Subtraction Property of Equality: We subtracted 2x on both sides]

4) x = -2 [Division Property of Equality: We divided both sides by 5]


Hope this helps!
