Solve

Answer 1

Solve |2x + 22| = |-6x + 6|

Answer 2

I know that x= -2 but what does the other part equal.

Answer 3

the answer is { 7, -2} but if anyone could explain it to me that would be great

Answer 4

(2x+22)=(-6x+6), or
-(2x+22) = -(-6x+6)

Answer 9

if you have an equation like:

|x| = |y|

then there are four solutions:

x = y
x = -y
-y = y
-x = -y

of which only two are unique:

x = y
x = -y

Answer 10

|2x + 22| = |-6x + 6|
factor out a 2

2|x+11| = |-6x+6|

-6x + 6 = 2(x+11) or -6x+6 = -2(x+11)
