Answer:
C. The expression is not equivalent, but it is completely factored.
5+x=-9
Use the subtractive property of equality to isolate x.
5+x=-9
-5 -5
x=-14
The value that satisfies x is -14. You can check your work by substituting x as -14 and checking if the equation is satisfied.
5+x=-9
x=-14
5+(-14)=-9
5-14=-9
-9=-9
the answer is correct. Succinctly, x=-14.
