Other answers:

we have |something|=positive
not |something|=negative
but you wrote or 2y-2=-15 ?
\[2y=17 => y=\frac{17}{2}\] \[2y=-13 => y=\frac{-13}{2}\] i wrote that because we have|something|=positive gives us two cases
oh ok but if it is |something| = negative then we have no soloution right?
right!
thanks for that was abit confused

|f(x)|>=0 so thats why |f(x)| can not have negative output
ok thanks :)
