Question

Solve: |2t + 5| = 3

Answer 1

Absolute values mean that what's inside the bars is equal to either the right side or the NEGATIVE of the right side.

Take this, for example,
|2t + 5| = 3
means either
2t + 5 = 3

OR

2t + 5 = -3


Solve both equations, and you're good to go :)

Answer 2

{1, -4}? @terenzreignz

Answer 3

Try it.
Replace the t in
|2t + 5| = 3
with 1 and -4
See if it adds up :)

Answer 4

{-1, -4}
