Question

Consider the lines 2x-y=0 4x+3y= 20 then the only common point of the both lines

Answer 1

Answer:

2x-y=0.............(1)

4x+3y=20..........(2)

slovs the above equation and obtain the value of x, y so the value of x, y gives the common point between them

so multiply eqn 1*3

6x-3y=0

4x+3y=20

add above eqn

10x=20

x=20/10=2

put the value of x in eqn 1

2*2-y=0

y=4

so common point bewteen them (2,4) ans....
