So we are given a system:

Substitute x = 2 we get the system:

Multiply the first equation by -5 and the second by 2 we get the system:

Adding the two equations we get :

We find the value of y by using any of the other equations like this:

Final solution:
Answer:
D and A
Step-by-step explanation:
96 - 12 is 24, then you divide by 12. A and D are the same but D is Just A simplified
Answer:
here x = 20 and y = 50.....
