Answer 2

Hi there mate!!

I hope this helps you

3x+y=9.......(1)

y=9-3x.....arranging the eqn 1

If x=2

Then y=9-3x

=9-3*2

=9-6

=3

Like wise take any nos.

And substitute it as x

2x+y=7.....(2)

y=7-2x.....arranging eqn 2

If x=2

Then y=7-2x

=7-2*2

=7-4

=3

Likewise take any nos.

And substitute it as x

Then solve it on graph paper
