Question

solve for x
-3|x+7|=-12

Answer 1

-12/-3?

Answer 2

|x|=x or -x

Answer 3

|x+7|=-12/-3
|x+7|=4
an absolute value can be broken down into 2 equations like so,
x+7 =4
or
x+7=-4

Answer 4

-3[x+7]=-12
x+7=4 and x+7=-4

Answer 5

since getting 4 or -4 in the absolute value will make it 4 after applying the absolute value function
