Question

How many solutions does the system have?

x = -4y + 4
2x + 8y = 8
A. one solution

B. two solutions

C. infinitely many solutions

D. no solution

Answer 1

C
when you simplify the first equation you get x=-4(y+1) and when you simplify the second one by dividing by 2 you get x+4y=4 or x=-4y+4 which gives x=-4(y+1) as well
