Answer:
(x, y) = (-4, 3)
Step-by-step explanation:
I would start by dividing the first equation by 3 (because you can).
-x -y = 1
Now, substitute the expression in the second equation for y:
-x -(-5x -17) = 1
-x +5x +17 = 1 . . . . . use the distributive property to eliminate parentheses
4x = -16 . . . . . . . . . . collect terms, subtract 17
x = -4 . . . . . . . . . . . . divide by 4
y = -5(-4) -17 = 20 -17 = 3 . . . . . substitute for x in the second equation
The solution is (x, y) = (-4, 3).
