Question

Solve.
3(x + 1) - 2x = -6.

Answer 1

3(x + 1)- 2x = - 6 (distribute the 3 through the parenthesis)
3x + 3 - 2x = - 6 (combine like terms)
x + 3 = - 6 (subtract 3 from both sides)
x + 3 - 3 = - 6 -3 (combine like terms)
x = - 9
check...
3(x + 1) - 2x = - 6
3(-9 + 1) - 2(-9) = - 6
3(-8) + 18 = - 6
-24 + 18 = - 6
-6 = -6 (correct)
ANSWER : x = - 9
