Step-by-step explanation:
The answer is is 24 5 +9=15+9=24
5(x-7) = 25
x-7 = 25/5=5
x = 5+7=12
Answer:
A. x = 0, x = -3, x = 2, and x = -2
Step-by-step explanation:

by moving the terms on the left side to the right side

factor an
from 
and factor - 4
from 
the equation becomes :
= 0
take
as a common factor the equation becomes :
= 0
thus
⇒
and
by factoring an x we get :
⇒
= 0 and 
⇒
and 
Thus
the values are :
x = 0, x = -3, x = 2, and x = -2
