Given that,
2x + 3y = 17 ...(i)
2x + 2 - 3y + 1 = 5
⇒ 2x - 3y + 3 = 5
⇒ 2x - 3y = 5 - 3
⇒ 2x - 3y = 2 ...(ii)
Now, adding (i) and (ii), we get
4x = 19
⇒ x = 19/4
Now, putting x = 19/4 in (i), we get
2 (19/4) + 3y = 17
⇒ 3y = 17 - 19/2
⇒ 3y = (34 - 19)/2
⇒ 3y = 15/2
⇒ y = 5/2
∴ the required solution be
x = 19/4 and y = 5/2
