The equation 3(4u+2)=−30 is solved in several steps below.For each step, choose the reason that best justifies it.

Question

Reasons for each step (to choose from):

1. Addition Property of Equality
2. Subtraction Property of Equality
3. Multiplication Property of Equality
4. Division Property of Equality
5. Simplifying
6. Distributive Property

Answer 1

3(4u + 2) = -30 <-- given

4u + 2 = -10 <--- division property of equality; divides both sides by 3

4u = -12 <--- subtraction property of equality; subtracts 2 from both sides

u = -3 <--- division property of equality; divides both sides by 4
