Question

Solve kx - 4 = 9 for x.

Answer 1

x = 13/k

Explanation:

1) Combine the constants, obtaining:

kx = 13

2) Divide both sides by k to isolate x:

x = 13/k

Answer 2

x = 13/k

Explanation:

kx - 4 = 9

Add 4 to each side

kx - 4+4 = 9+4

kx = 13

Divide each side by k

kx/k = 13/k

x = 13/k
