-3(x + 15) + 4 – 5x = 2 + 10x - 7
First, apply the distributive property to solve the parentheses:
-3(x)-3(15)+4-5x=2+10x-7
-3x -45 +4 -5x = 2 +10x -7
Move the "x" terms to the left side of the equation:
-3x -5x -10x = 2-7 +45 -4
-18x = 36
Divide both sides by -18:
-18x/-18 = 36/-18
x = - 2 (option b)
