Question

x+2y-4 equal to 0 2x+y-9 equal to 0​

Answer 1

x+2y-4=0. ....(1)

2x+y-9=0. .....(2)

From eqn (1)

x+2y=4

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

Putting the value of x in eqn (2)

2(4-2y)+y-9=0

8-4y+y-9=0

-1-3y=0

-3y=1

y=-1/3

putting the value of y in eqn (3)

x=4-2(-1/3)

x=4+2/3

x=13+2/3

x=15/3

x=5
