Here are the original equations:
(i) 2x+-+3y+=+-1
(ii) 1y+=+x+-+1
---
step 1 get x and y on the same side and lined up.
(iii) 2x++-+++3y+=+-1
(iv) -1x+%2B+1y+=+-1
---
step 2 - multiply second equation by 2 and add down.
(iii) 2x+-+3y+=+-1
(v) -2x+%2B+2+y+=+-2
Now,
-1y = -3 - -> Y = 3.
---
step 3 - sub this value into any above equation to get x.
x = 4.
