Question

Solve 2x-3y-6=0 and x-2y-5=0

Answer 1

2x-3y-6=0
2x-4y-10=0

2x-3y-6-2x+4y+10=0

y+4=0

y=-4

from eq. 2-

x=8-5

x=3

Answer 2

Multiplying the 2nd equation with 2 and then subtact both the equation.

2nd equation will become 2x-4y-10=0, And now subtact both the equation.

2x-4y-10-(2x-3y-6) = 2x-4y-10-2x+3y+6 = -y-4=0 》》 -y =4 = y= -4.

Put the value of y in any of the two equation and obtain the value of x which will be -3
