Answer:
x=-5 y=15
Step-by-step explanation:
First combine like terms and put the equations in standard form.
-6x - y = 15
5x - 2x + 2y - y = 0 equals 3x + y = 0 equals y = -3x
Go into the first equation and substitute -3x for y
-6x - (-3x) = 15
Simplify: -6x + 3x = 15
-3x = 15
x = -5
Now put -5 in for x and solve for y.
y= -3 (-5)
y=15
