Question

If (2, 0) is the solution of 2x + 3y = k then finds the value of k by completing the activity

Solution: (2, 0) is solution of the equation 2x + 3y = k

Putting x = `square` and y = `square`

∴ `2(square) + 3 xx 0` = k

∴ 4 + 0 = k

∴ k = `square`

Answer 1

(2, 0) is solution of the equation 2x + 3y = k

Putting x = 2 and y = 0

2(2) + 3 × 0 = k

∴ 4 + 0 = k

∴ k = 4
