Question

How to solve 2x+3y=4 and 3x-y=-5 by graphical method??

Answer 1

Answer:

Step-by-step explanation:

take 2x+3y=4

x=4-3y/2 equation 1

now take 3x-y=-5

substitute equation 1  

3(4-3y/2)-y=-5

12-9y-2y/2=-5

12-9y-2y=-10

-11y=22

y =-2 equation 2

substitute equation 2 in equation one

x=4-3y/2

x= {4-3(-2)}/2    = 4/2+6/2
