We can't tell where your parentheses are, so we don't know if you said 5 (x+2) = 17 or (5x+2)=17.
... If it's the first one, then x+2=17/5 and x=7/5 or 1.4. / / / If it's the second one, then 5x=15 and x=3.
I guess it must be the second one, because 1.4 is not one of the choices. Ah the sleaze of math by multiple choice.
