Answer:
Explanation:
3(x + 1) = 5x + 6.....distribute the 3 thru the parenthesis
3x + 3 = 5x + 6....subtract 3x from both sides
3 = 5x - 3x + 6...subtract 6 from both sides
3 - 6 = 5x - 3x....combine like terms
-3 = 2x...divide both sides by 2
-3/2 = x
check...
3(-3/2 + 1) = 5(-3/2) + 6
3(-3/2 + 2/2) = -15/2 + 6
3(-1/2) = -15/2 + 12/2
-3/2 = -3/2 (correct)...so it checks out
x = -3/2
