What is the solution of the system? use elimination.
7x+5y=19
-7x-2y=-16
a. (–2, –1)
b. (–2, 1)
c. (2, 1)
d. (2, –1)

C (2,1)

Step-by-step explanation:

7x+5y=19

-7x-2y=-16

Add both equations together to eliminate x

7x+5y=19

-7x-2y=-16

   3y = 3

Divide each side by 3

3y/3 = 3/3

y =1

Now we need to find x

7x+5y = 19

7x +5 = 19

Subtract 5 from each side

7x+5-5=19-5

7x=14

Divide by 7

7x/7 = 14/7

x=2

(2,1)
