Question

Solve using elimination

-2x+4y=-16
-2x-y=19​

Answer 1

x = -6 y = -7

Explanation:

multiply the 2nd equation by -1 to get 2x + y = -19

Now -2x + 4y = -16

2x+y = -19

5y = -35

y = -7

Substitute y = -7 into the second equation to get -2x + 7 = 19

-2x = 12

x = -6

Check: Substitute values into the 1st equation

-2(-6) +4(-7) = 12 - 28 = -16

So we have the correct values for x and y

Answer 2

Elimination is getting rid of one of the variables the answer is (-6,-7)
