-3x-5y=6 ...eq.1
y=-3......eq.2...plug in eq.1
_________________
-3x-5%28-3%29=6
-3x%2B15=6
15-6=3x
9=3x
9%2F3=x
3=x
solution,x=3 and y=-3


y=-6x-3 ...eq.1
y=-x%2B2...eq.2
_____________________subtract
y-y=-6x-3-%28-x%2B2%29
0=-6x-3%2Bx-2
0=-5x-5
5x=-5
x=-1
find y
y=-%28-1%29%2B2...eq.2
y=1%2B2
y=3
solution,x=-1 and y=3
