Answer:

x=-2 see explanation below:

Step-by-step explanation:

2x+4=5(-4-2x)

2x+4=(5*-4)(5*-2x)  

2x+4=-20-10x

    -4        -4

2x=-20-4-10x

+10x       +10x

2x+10x=-20-4

12x=-24

-----   -----

12      12

x=-2

Check:

2x+4=5(-4-2x)

Substitute -2 for x:

2(-2)+4=5(-4-2(-2))

Solve:

2(-2)+4=5(-4-2(-2))

-4+4=5(-4+4)

-4+4=5(0)

0=0

Therefore x does in fact equal -2
