Question

Solve : 2x+3y+4=0 and x-5y=11 by graphical method​

Answer 1

Answer:

Step-by-step explanation:

2x + 3y + 4 =0.

x - 5y = 11.

from equation

x = 11+5y

substitute x value in equation (1)

2 ( 11+5y ) + 3y + 4 = 0

22 + 10y + 3y + 4 = 0

26 + 13y = 0

13y = -26

y = -26/13

y = -2

substitute y value in equation (3)

x = 11+ 5y

x = 11 + 5 (-2)

x = 11-10

x = 1
