This ax+-+b+=+c is a problem that looks quite intimidating but it is really quite simple, as long as you are not intimidated by the ugly answer that you get.

In order to "undo" the subtraction of b, you should start by adding "+b" to each side of the equation:
ax+-+b+=+c
ax+-+b+%2B+b=+c%2Bb
ax+=+c%2B+b or ax=+b%2B+c (either way is acceptable!)

Next, since you have "ax", which means "a times x," you must undo this by dividing both sides by a. The result looks like this:
+%28ax%29%2Fa+=+%28c%2Bb%29%2Fa+
+x+=+%28c%2Bb%29%2Fa+ or x+=+%28b%2Bc%29%2Fa
