Solving for x in terms of other variables YO CPhill, this is for you

yx-a=cx    add a to both sides

yx  = cx + a     subtract  cx from both sides

yx - cx = a    factor out x on the left

x( y - c)  = a    divide both sides by (y - c)

x =  a /(y -c)

yx-a=cx

I need x in the terms of the others, thanks.

x = -a/(c-y)

could you show the work, I am confused

Here it is step by step:

Solve for x:
x y-a = c x
Isolate x to the left hand side.
Subtract c x-a from both sides:
x (y-c) = a
Solve for x.
Divide both sides by y-c:
Answer: | 
| x = a/(y-c)
