Answer:

1) (5,2)

2) (3,1)

3) (4,2)

Explanation:

Set the equations equations equal to each other. Since you have 2 different values of y, you can plug the second equation of y into the first equation of y

The first one would be x-3=2 (2 is substituted for y) to get x=5

After finding the x value, plug it back into either equation again to get 5-3=2 (In this case y is already given to you)

The second one would be 2x-5=-(2/3)x+3

2x-8=-(2/3)x

3x-12=-x

4x-12=0

x=3

y=2(3)-5=1

(3,1)

The last one would be (1/2)x=2x-6, solving gives x=4x-12

3x-12=0

x=4

y=2(4)-6

y=2

(4,2)
