Question

35. In a given Equations
x - y + 3 = 0 and 2x – y + 9 = 0. Find their solution graphically​

Answer 1

Answer:

x-y+3=0

x-y=-3

x=-3+y----(1)

2x-y+9=0

using eq. (1)

2(-3+y)-y+9=0

-6+2y-y+9=0

y=-3

putting the value of y in eq 1.

then,

x=-3-3

x=-6

Hence, x=-6 and y=-3.

if you satisfied with my answer then make it brilientlist.

Answer 2

:x = 3

X +y=9 eqn 1

2x -y=0. Eq n 2

3x =9

X=9by 3

By dividing we get 3
