Question

If -2(3y+5)=-4, find the value of 5y

Answer 1

First, solve for y

1. Distribute the -2 using the distributive property
-2 x 3y + -2 x 5 = -4
-6y - 10 = -4

2. Combine like terms by adding 10 to both sides.
-6y = 6

3. Solve for y by dividing both sides by -6
y = -1

Second, plug your answer into 5y
5(-1) = -5

5y = -5
