Question

2x-2y=-14
x+2y=-1

Answer 1

Solve the following system of equations:

x − 2y = 14..................(i)
x + 3y = 9 ..................(ii)
from (i) x =2y+14.......(iii)
Put the value of x from (iii) in (ii)
2y+14 +3y = 9
5y = -5 or y = -1......................Ans
From (iii) x = -2+14 12...........................Ans

(1, 12)

(−1, −12)

(12, −1)..............................Ans
(12, 1)
