Answer:

X=-9

Explanation:

Isolate x on one side of the equation.

-2(x+7)=4

DISTRIBUTIVE PROPERTY:

A(B+C)=AB+AC

A(B-C)=AB-AC

-2(x+7)/-2=4/-2 (First, divide by -2 from both sides.)

4/-2 (Solve.)

4/-2=-2

x+7=-2

x+7-7=-2-7 (Then, subtract 7 from both sides.)

-2-7 (Solve.)

-2-7=-9

x=-9

So, the final answer is x=-9.
