1.) y=6+11
y=6-11
y=-5
-2x-3y=-7
-2x-3(-5)=-7
-2x+15=-7
-2x=-7-15
-2x=-22
-2x/-2=-22/-2
x=11
y=-5
(You can check it if it is truly correct or not. But, in Math, checking is just an option.)
2.) y=5x-7
-3x-2y=-12
-3x-2(5x-7)=-12
-3x-10x+14=-12
-13x + 14 =-12
-13x=-12-14
-13x =-26
-13x/-13=-26/-13
x = 2
y=5x-7
y=5(2)-7
y=10-7
y=3
So:
x=2 and y=3
3.) -4x + y=6

x=-3
-4x+y=6
-4(-3)+y=6
12+y=6
12-6=-6
y=-6
x=-3 and y=-6
y=6-11
y=-5
-2x-3y=-7
-2x-3(-5)=-7
-2x+15=-7
-2x=-7-15
-2x=-22
-2x/-2=-22/-2
x=11
y=-5
