Question

ax-x=c Find X

Answer 1

1) Subtract ax from both sides.
2) Multiply both by -1.

Answer 2

\[ax - x = c\] \[\implies -x = c - ax\] \[\implies x = -(c - ax) \] Does that help?

Answer 3

You need learn how to factor.

Answer 4

x(a - 1) :O oh yes

Answer 5

So, there'd be two solutions. One by factoring it and then dividing both sides by a - 1(special creds to @across) and then the one I mentioned.

Answer 6

Your approach is intuitive, but the issue with it is that you're defining \(x\) in terms of \(x\). In other words, it's like you're defining a dictionary word using the word you're defining. :P

Answer 7

Ha, yes.
