I have read my tutorial book over and over but i still cannot understand how to make

*k *the subject of the below

equation.

I really need to understand how this works so please do not give me any answers - just direct me and explain where I go wrong.

The question asks I make

*k *the subject of;

*t=* 9*s*/5+4*k*
I begin by multiplying both sides by (5+4

*k*) giving

*t**(5+4

*k*) = 9

*s*/5+4

*k**(5+4

*k*)

Simplifying gives me

*t*(5+4

*k*)=9

*s *(i think)

multiplying both sides gives me

5

*t*+4

*kt*=9

*s*
I want to find all the terms that contain the required subject, k, and move them to the left.

4

*kt*=5

*t*+9

*s*
Now i want to subtract and then divide by t which gives

*k*=5

*t*-9

*s*/4

*t*
Im stabbing in the dark with parts of this equation. Any direction would be appreciated
