Johan found that the equation -2|8-x|-6=-12 has two possible solutions: x=5 and x=-11. which explains wether his solutions are correct

-2|8-x|-6=-12

-2|8-x|=-6

|8-x|=3

8 - x = 3 and 8 - x = -3

8 - x = 3

-x = -5

x = 5

8 - x = -3

-x = -11

x = 11

Johan's second solution is incorrect.

The solution is x = 5 and 11

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,

mrb
