Question

Solve by elimination:
x-3y=16
-5x+3y=-20

Answer 1

x = 1

y = -5

Explanation:

x - 3y = 16

-5x + 3y = -20

Combine the equations

-4x = -4

x = 1

Now put 1 in for x and solve for y

1 - 3y = 16

-3y = 15

y = -5

Let's Check

1 - 3(-5) = 16

1 + 15 = 16

16 = 16

SO, x = 1 and y = -5 is the correct answer.
