Answer:

x = -20

Step-by-step explanation:

1st Subtract 8 from both sides: 84/5(15+2x)-8=-12-8

2nd Simplify: 4/5(15+2x)=-20

3rd Multiply both sides by 5: 5×4/5(15+2x)=5(-20)

4th Simplify: 4(15+2x)=-100

5th Divide both sides by 4: 4(15+2x)÷4=-100÷4

6th Simplify: 15+2x=-25

7th Subtract 15 from both sides: 15+2x-15=-25-15

8th Simplify: 2x= -40

9th Divide both sides by 2: 2x÷2=-40÷2

10th Simplify: x = -20
