Thank you for the opportunity to help you with your question! Hope your day is going well!

Equation 1: 2x-y=0

Equation 2: 3x-y=3

Solve for y in equation 1

2x-y=0

-y=-2x

y=2x

Substitute y=2x into equation 2

3x-2x=3

x=3

Substitute x=3 into equation 1

2(3)-y=0

6-y=0

6=y.

Check your work

2(3)-6=0 check

3(3)-6=3 check!

Thus our order pair is (3,6)
