Answer
$x=-2$
$y=-10$
Work Step by Step
Equation 2 is already solved for y, we substitute y in the first equation, with the expression in the second:
$2x-y=6$
$2x-5x=-3x=6$
$x=-2$
$y=5x=-10$
We need to check, if it is the right solution, we substitute x with -2 and y with -10:
$2(-2)-(-10)=-4+10=6$ $\checkmark$
$-10=5(-2)$ $\checkmark$
