Question

Which are the solutions to the equation |2x + 3| - 5 = 12?

Answer 1

First you keep isolate the absolute value

|2x + 3| = 17

Then you make two equations and solve.

The first equation is:

2x + 3 = 17

2x = 14

x = 7

The second equation would be:

2x + 3 = -17

2x = -20

x = -10

Answer 2

So the solutions are x=7 and x= -10
