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
