Answer
$x=-1$
$y=4$
Work Step by Step
Equation 2 is already solved for y, we substitute y in the first equation, with the expression in the second:
$-3x-5y=-17$
$-3x-5(4x+8)=-23x-40=-17$
$-23x=23$
$x=-1$
$y=4x+8=4$
We need to check, if it is the right solution, we substitute x with 2 and y with 3:
$-3(-1)-5(4)=-17$ $\checkmark$
$4=4(-1)+8$ $\checkmark$
