Question

Solve for x: 5|2x − 2| + 8 = 18.

x = 2, x = −2
x = −2, x = 0
x = 2, x = 0
x = 0, x = 1 over 2

Answer 1

remember
|x| makes x posotive
5|2x-2|+8=18
minus 8 both sides
5|2x-2|=10
divide both sides by 5
|2x-2|=2
assume
2x-2=2 and 2x-2=-2

2x-2=2
add 2
2x=4
divide 2
x=2

2x-2=-2
add 2
2x=0
x=0


x=0 or x=2
