Writing the given equations in standard form :

∴2y+x=7

⇒

7/2

y

+

7

x

=1

so y intercept will be 7/2 = 3.5

and x intercept will be 7

2x+y=8

⇒

4

x

+

8

y

=1

so y inetrcept will be 8

x inetrcept will be 4

finding point of intersection :

2y+x=7

x=7−2y ... (1)

2x+y=8

from equation (1)

2(7−2y)+y=8

14−4y+y=8

3y=6

y=2

∴x=3
