x-15, x represents the unknown number, and to have 15 less you would simply subtract 15 from x.... therefore your answer is x-15
There is no need for a conditional expression; just write it as 10 * 100.
The algebraic expression is n + 100, where n is the unknown number.
If x is the unknown variable then it can be: x-16
s divided by 6
n*5 - 6

The variable represents either a variable amount, or an initially unknown amount. Converting a word problem to an algebraic equation requires some practice. Here is a simple example:If I earn an additional $10, I'll have $50. How much do I have now? The amount I have now is the unknown; obviously, if I add $10 to that, I'll have $50. So (omitting the dollar signs), I call this unknown amount "x" (or some other variable), and write: x + 10 = 50
