JamesJ, dont be mad you cant solve it

Answer 4

Take a step back, what is the definition of |x|?

Answer 5

@ivan514, don't be absurd. Of course I can solve it.

Answer 6

ok so lets not attack the mod and lets explain.

As James has said what is the definition of |x| +/-x right?

|5x + 2| = 13

5x + 2 = 13

5x+2 = -13

Answer 7

right. Konrad, take it from here, thanks.

Answer 8

-2 from both sides

5x = -15
5x = 11

divide both sides by 5

-15/5 = x
11/5 = x

-3 = x

11/5 = x
