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
