Question

Solve the system of equations​

Answer 1

X= 15/8

Y= 17/2

Explanation:

If you plug in the y equation into the 4x equation you will get the answer to x and then plug in the x to get the value of y.

Answer 2

y=17/2 and x=15/8

Explanation:

By subsitution, we get 4x+4x+1=16, so 8x=15. Thus, x=15/8. Next, we plug x in to find y. y=4*15/8 +1, or 15/2 +1 = 17/2
