Question

Which of the following equations is the result of cross multiplying the given proportion?

(3)/(k+3)=(8)/(k-2)


3k - 2 = 8k + 3
3k - 6 = 8k + 11
3k - 6 = 8k + 24

Answer 1

3k -6 = 8k+24

Explanation:

3 8

---------- = ---------

k+3 k-2

Using cross multiplication

3 * (k-2) = 8 * (k+3)

Distribute

3k -6 = 8k+24

Answer 2

(3)/(k+3)=(8)/(k-2)

Cross multiply:

3(k-2) = 8(k+3)

Simplify:

3k -6 = 8k +24
