Put the a"s to one side of the equation and the non-a's to the other side
Explanation:
-a - 3 + 7 = 3a
-a - 3a = - 7 + 3
-4a = -4
a = 1
The solution is 1. Below I have included a few problems for you to practice with, of the same sort.
A) 3x + 36 = 18 - 3x B) 2x + 2 = 5x + 8
C) -4x - 13 = -12x + 3 D) 2x - 8 = -4x + 4
