Step-by-step explanation:
3x-2y =1
x+y=2 ; y=2-x
3x-2(2-x)=1
3x+2x-4=1
5x=5
x=1
y=2-x.; y= 2-1=1
x=1,y=1

If we take second equation which is x+ y = 2
Which gives us x= 2-y
Substituting in eq ist
3(2-y)-2y=1
6-3y-2y= 1
6-5y= 1
5= 5y
Which gives us x= 2-y
Substituting in eq ist
3(2-y)-2y=1
6-3y-2y= 1
6-5y= 1
5= 5y
