Question

Solve for x: |2x + 6| − 4 = 20
@satellite73 would this be no solution?

Answer 1

no this one you can solve

Answer 2

okay can you walk me through on how to solve this or similar? absolute values confuse me

Answer 3

\[|2x+6|=16\] is a start
then
\[2x+6=16\] or
\[2x+6=-16\] solve for \(x\)

Answer 4

x=-5

Answer 5

Quick hint: Always get your absolute values by themselves on one side of the equation.

In this case, just add 4 to both sides to do that first.

Answer 6

Sorry to interrupt @satellite73, I leave you to your excellent work.

Answer 7

so 2x+6=24?

Answer 8

oh no i made a huge mistake didn't i?

Answer 9

\[|2x+6|-4=20\\
|2x+6|=24\] so
\(2x+6=24\) or \(2x+6=-24\)
