Question

I REALLY NEED HELP!!!!!

Answer 1

1) 8(3a+6) = 9(2a-4)

First, we use distributive property on both sides.

Once we do this, we get:

24a + 48 = 18a - 36

Add 36 to each side.

24a + 84 = 18a

Subtract 24a from each side.

84 = -6a

Divide each side by -6

-14 = a

2) 6(2x-8)+3 = 15

Again, we use distributive property:

12x-48+3 = 15

Subtract 3 from each side

12x - 48 = 12

Add 48 to each side

12x = 60

Divide each side by 12

x = 5

3) -5(3x+6) = -3(4m-2)

Distributive property:

-15m - 30 = -12m + 6

Add 30 to each side

-15m = -12m + 36

Add 12m from each side

-3m = 36

Divide each side by -3

m = -12
