Question

The value of a for which (3.a) lies on 2x-3y=5 is
a)1/3
b)3
c)-1/3
d)-3​

Answer 1

Given:

The equation 2x-3y=5

lies (3,a)

Step-by-step explanation:

take x=3,y=a

2(3)-3(a)=5

6-3a=5

taking 6 from left side to right side to substitute the constant value.

-3a=5-6

-3a=-1

multiple both side by " -"

3a=1

taking 3 from left side to right side to get value of  a

a=1/3

the value of a=1/3.
