Answer:
The given equations are x + 2y = – 1 ..(i) and 2x – 3y = 12 …(ii) From (i) x = – 1 – 2y …(iii) Substituting this value of x in (ii), we get 2( – 1 – 2y) – 3y = 2 ⇒ – 2 – 4y – 3y = 12 ⇒ – 7y = 14 ⇒ y = -2 Putting y = – 2 in (iii), we get x = -1-2×(-2) = -1+4 = 3 Hence the required solution is x = 3 and y = –
