SSC 1. Solve the given system of equationsby elimination method :x + 2y + 1 = 02x - 3y - 12 = 0

Answer»

x + 2y = -1 . . . . . (1)

2x - 3y = 12 . . . . . (2)

(1) × 2

2x + 4y = -2 . . . . . (3)

(2) - (3)

-7y = 14

y = -2

Substitute in (1)

x + 2(-2) = -1

x - 4 = -1

x = 3

x=3,y=-2.....like plz for ppints
