If (2, 0) is a solution of the linear equation 2x + 3y = k, then the value of k is
a. 4
b. 6
c. 5
d. 2

Solution:

The given linear equation is

2x + 3y = k

The point given here is

(x, y) = (2, 0)

Let us substitute the given values in the equation

2 (2) + 3(0) = k

By further calculation

4 + 0 = k

So we get

k = 4

Therefore, the value of k is 4.

✦ Try This: If (3, 0) is a solution of the linear equation 4x + 6y = 2k, then the value of k is a. 4, b. 6, c. 5, d. 2
