Answer:

-10

Step-by-step explanation:

4(x+3)=2x-8

4x+12=2x-8

Subtract 2x from both sides

2x+12=-8

Subtract 12 from both sides

2x=-20

Divide both sides by 2

2x=10

The solving process without the words:

[tex]4(x+3)=2x-8\\4x+12=2x-8\\-2x -2x \\2x+12=-8\\-12 -12\\2x=-20\\\frac{2x}{2} =\frac{-20}{2} \\x=-10[/tex]
