Answer:
y=17/2 and x=15/8
Step-by-step 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
X= 15/8
Y= 17/2
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.
