Solve the system of equations using elimination.

Mathematics
1 answer:
olasank [31]3 years ago

Answer:

The solution would be D) (5, -8)

Step-by-step explanation:

To use this method, start by multiplying the second equation by -1. Then add the two equations together.

8x + 7y = -16

-10x - 7y = 6

------------------

-2x = -10

x = 5

Now that we have the value of x, use it to solve either equation for y.

10x + 7y = -6

10(5) + 7y = -6

50 + 7y = -6

7y = -56

y = -8
