kx + 9 = 7 for x

To solve for x in the equation kx + 9 = 7, we can isolate the variable x by performing the following steps:

1. Subtract 9 from both sides of the equation:
kx + 9 - 9 = 7 - 9
kx = -2

2. Divide both sides of the equation by k:
(kx) / k = -2 / k
x = -2 / k

Therefore, the solution for x is x = -2 / k.
