Question

the point (3,a) lie on the line 2x-3y=5 then the value of a is *

1/2

1/3

1/4

1/5
The pair of equation 2x-5y+4=0 and 2x+y-8 =0 has *
a unique solution
exactly two solutions
infinite many solutions
no solution​

Answer 1

Answer:

1. a=1/3

2. Infinite many solutions

Step-by-step explanation:

1. 2x-3y=5

-3y=5-2x

y=(5-2x)/-3

y=-5+2x/3

Put x=3

y= -5+2(3)/3

y= (-5+6)/3

y=1/3

y=a=1/3

a=1/3

2. Infinite many solutions (because there can be many lines which can pass through a line)
