Question

2x-3y=9;x+y=7make graph and find the value of x and y​

Answer 1

Step-by-step explanation:

Sorry I can't draw a graph but I would find value of x and y

2x-3y=9. ×1. equ.1

x+y=7. ×2. equ.2

______

2x-3y=9

2x-6y=14

(-). (+). (-)

_________

3y=5

y=5/3

Now put the value of y in any equation

I am putting the value of y in equation 2

x+y=7

x+5/3=7

x+5=21

x=21-5

x=16

So,the value of x is 5/2 and value of y is 16

(x,y)=(5/2,16)

Hope it will be help you
