Steps to solve:
-3(x + 2) = 12
~Distributive Property
(-3 * x) + (-3 * 2) = 12
~Simplify
-3x - 6 = 12
~Add 6 to both sides
-3x - 6 + 6 = 12 + 6
-3x = 18
~Divide -3 to both sides
-3x/-3 = 18/-3
x = -6
Best of Luck!
Answer:
x = 114°
Step-by-step explanation:
x = 114
vertical angles are equal
9x + 8
2(3x + 1) + 5x + 9 - 2x - 3
⇒ 6x + 2 + 5x + 9 - 2x - 3
⇒ 9x + 8
