-5x + y = -12

- 3x + 6y = -12

Since both of expressions have a value of -12, their sum is - 24. This is true only when

x = 20/9 and y = -8/9.

-5x + y = -12

y = 5x - 12

- 3x + 6y = -12

-3x + 6(5x - 12) = -12

-3x + 30x - 72 = -12

27x = 60

x = 60/27

x = 20/9

y = 5x - 12

y = 5(20/9) - 12

y = 100/9 - 12

y = (100 - 108)/9

y = -8/9
