Question 9135: solve for x in terms of the other variables
ax-b=x+c

You can put this solution on YOUR website!
ax-b=x+c

Get all the terms with x in them on one side. Get all the other terms on the other side...

ax-b-x = c
ax-x = c+b

This says "a" lots of x minus "1" lot of x...you cannot do this...one is a letter, the other a number. Tough!

What we can do is re-write it, by factorising:

x(a-1) = b+c

so that x = (b+c)/(a-1)

Note i have added the brackets so you know that b+c is together as are a-1.
