( Multi-step Equations)
please help:)<3​

Answer 1

x = -7/2

Explanation:

-3(4x + 9) = 15

Divide 3 on both sides

-3(4x + 9) /3 = 15 /3

Which makes

4x+9=-5

Subtract 9 on both sides

4x+9 -9 = -5 -9

Which makes

4x=-14

So we divide 4

4x /4 = -14 /4

And we get......

x = -7/2

I hope it's right!

Answer 2

Explanation:

-3(4x + 9) = 15

-12x-27=15
