Question

X+2y+1=0 2X-3y-12=0​

Answer 1

Answer:

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

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

multiplying 3 in eqn. (1) and 2 in eqn. (2) we get

3x+6y = -3 -------(3)

4x-6y = 24 -------(4)

adding eqn. (3) and (4) we get

7x = 21

so x = 21/7 = 3

putting x=3 in eqn. (1) we get

2y= -1-3 = -4

so y= -2
