Question 562152: Make a two column proof to prove that x=-1 if 5(3-2x)=28+3x

We want to prove that if 5(3-2x) = 28+3x, then x = 1 (note the conditional).

5(3-2x) = 28+3x <--> Given

15-10x = 28+3x <--> multiplication is distributive over addition/subtraction

-13 = 13x <--> addition property of equality (I applied this twice for sake of space)

-1 = x <--> division property of equality
