Substitute 4 and then - 4 for x in the equations y=x+1 and 2y-2+=2x. Describe the results

Basically both equations can get you the same answer

Step-by-step explanation:

for the first

y=x+1

y=4+1

y=5

y=-4+1

y=-3

for the second

2y-2=2 (4)

2y-2=8

2y=8+2

2y=10

y=5

2y-2=2 (-4)

2y-2=-8

2y=-8+2

2y=-6

y=-3
