Question

Solve for x: |2x + 6| − 4 = 20

Answer 1

isolate |2x+6| to one side by adding +4 to both sides. \[|2x+6| = 24\]

Answer 2

Add 4 to both sides.
|2x+6|−4+4=20+4
|2x+6|=24
Solve Absolute Value.
|2x+6|=24
We know either 2x+6=24 or 2x+6=−24

Answer 3

isolate |2x+6| to one side by adding +4 to both sides.
what do you think is anwser

Answer 4

Now the absolute value means that x has 2 answers,

-(2x+6) =24 or 2x+6 =24
