Answer:

B) -4

C) -5

Explanation:

B)

So we have:


3(2x+4)=-12

First, divide both sides by 3. The left side cancels:


2x+4=-4

Subtract 4 from both sides. The left side cancels:


2x=-8

Divide both sides by 2. The left side cancels:


x=-4

C)

We have:


4(5-2x)=60

Divide both sides by 4, the left side cancels:


5-2x=15

Subtract 5 from both sides:


-2x=10

Divide both sides by -2:


x=-5

And we're done!
