Question

Solve -6x-2y=38-x-3y=9 A) (–6, 1)
B) (–1, 6)
C) (9, –6)
D) (–6, –1)

Answer 1

Solve for x or y and plug it back in to the respective variable.

Answer 2

so first, you're going to put all the x on one side, and all the y on the other.
Let's add 6x and 3y to both sides, which will gives you:
y= 5x + 38 = 9 Now, subtract 9 from both sides, which gives you:
y= 5x + 29
From that equation above, plug the points (x,y) in and see if the coordinates matches.
1 = 5(-6) + 29 WRONG!
6 = 5(-1) + 29 WRONG!
-6 = 5(9) + 29 WRONG!
-1 = 5(-6) + 29 CORRECT!
