Solve 5kx + 6 = 7kx for x.

5kx + 6 = 7kx  

Subtract 6 on both sides  

5kx + 6 - 6 = 7kx - 6

5kx = 7kx - 6

Then subtract 7kx on both sides

5kx - 7kx = 7kx - 6 - 7kx  

-2kx = -6  

Now divide by -2k on both sides

-2kx/-2k = -6/-2k

x = -6/-2k

Simplify

x = 3/k  

These are algebriac equations that you keep doing. Maybe try practicing the simpiler algebriac equations then slowely do more complicated ones. Just letting you know.
