Answer 2

Question:

• Find the value of k, if (2,1) is the solution of the linear equation 3x=ky-9. hence express the equation in the form of ax+by+c +0.

To Find: Value of k.

Solution:

Let us consider that (2,1) is (x,y)

Then,

→ 3x = ky -9

→ 3x -ky + 9 = 0

→ 3(2) - k(1) + 9 = 0

→ 6 - k + 9 = 0

→ -k + 15 = 0

Multiplying the -k with + ,we get:

→ k - 15 = 0

→ k = 15

• Therefore,The value of k is 15.
