Solve the system of equations using elimination.
1 answer:
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
