ANSWER

Since (3,a) lie on the line 2x - 3y = 5 ...(1)

Since (3,a) lie on the line 2x - 3y = 5 ...(1)Substituting x=3 and y=a in (1) we get

Since (3,a) lie on the line 2x - 3y = 5 ...(1)Substituting x=3 and y=a in (1) we get 2(3) - 3(a) = 5

Since (3,a) lie on the line 2x - 3y = 5 ...(1)Substituting x=3 and y=a in (1) we get 2(3) - 3(a) = 5 6 - 3a = 5

Since (3,a) lie on the line 2x - 3y = 5 ...(1)Substituting x=3 and y=a in (1) we get 2(3) - 3(a) = 5 6 - 3a = 5⇒3a=1

Since (3,a) lie on the line 2x - 3y = 5 ...(1)Substituting x=3 and y=a in (1) we get 2(3) - 3(a) = 5 6 - 3a = 5⇒3a=1⇒a=1/3.
