Question

Solve using elimination.
-2x - 5y = -2
-x - 5y = -11

Answer 1

x = -9

y = 4

Explanation:

-2x - 5y = -2

-x - 5y = -11

Time the second equation by -2

-2x - 5y = -2

2x + 10y = 22

5y = 20

y = 4

Now put 4 in for y and solve for x

-2x - 5(4) = -2

-2x - 20 = -2

-2x = 18

x = -9

Let's check

-2(-9) - 5(4) = -2

18 - 20 = -2

-2 = -2

So, x = -9 and y = 4 is the correct answer.
