Answer 3

ugh nvm..i'll do it myself..

Answer 4

for graphing, visit

I get C,A,B
Just plug in the numbers to make sure they work!

Answer 5

#5 is correct

#6
2x - 1 = x+3
x = 4 , y = 7
looks like A)

#7
4x = 5-x
5x=5
x=1 , y = 4
looks like B)

You should have checked each of your answers by simply subbing your answer. It must satisfy BOTH equations
