Question

2x+3y=8and 6x+ky=24 so what whaylu of k

Answer 1

Answer:

• The value of k is 9.

Given:

• Give equations are

• 2x + 3y = 8 and 6x + ky = 24

To find:

• The value of k.

Solution:

=> 2x + 3y = 8...(1)

=> 6x + ky = 24...(2)

Multiply equation (1), by 3 we get

=> 6x + 9y = 24...(3)

Subtract equation (3) from equation (1), we get

=> ky - 9y = 0

=> y (k - 9) = 0

Divide both sides by y, we get

=> k - 9 = 0

=> k = 9

Therefore, the value of k is 9.
