Please help its just those 2 i need help on​

Answer 1

Answer:

B) -4

C) -5

Step-by-step 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!
