Question

How many solutions does the system have? y=4x-8 4y=4x-8

Answer 1

Answer:x=2,y=0

Explanation:

4(4x-8)=4x-8

16x-4x=32-8

12x=24

X=2

Y=0

Answer 2

There is one solution (x=2, y=0)

Explanation:

y=4x-8

4y=4x-8

Divide the second equation by 4

y = x - 2

Set the two equations equal

4x - 8 = x-2

Subtract x from each side

3x -8 = -2

Add 8 to each side

3x = 6

Divide by 3

x = 2

Now find y

y = x-2

y = 2-2=0
