Question

5.How many solutions does the system have?
x - y=4
2x - 2y = -8
a. one solution
b. two solutions
c. infinitely many solutions
d. no solution

Answer 1

Answer:

one solution = a, that is your answer

Answer 2

Answer:

D) No solution

Step-by-step explanation:

That is because...

x-y=4              2x-2y= -8

-y= -x+4          -2y= -2x-8

y= x-4              -y= -x -4

                       y=x+4

y=x-4 does not equal to y=x+4
