Replace 2x-y= 1 with y = 5-x.

2x-(5-x)= 1

2x-5+x= 1

3x=6

x=2

Substitute x=2 into x+y=5 to get y=3.

So, x=2, y=3.

2. Multiply both sides of the equation x/3-y/2= 1 by 6 at the same time to get

2x-3y=6

Multiply both sides by 3 at the same time and you get

6x-9y= 18 - ( 1)

Multiply both sides of 3x+2y=22 by 2 at the same time, and you will get

6x+4y=44 - (2)

( 1)-(2)

- 13y=-26

So y=2

Substitute y=2 into (1) to get x=6.

x=6，y=2
