We put this into an algebraic equation, where <span>x = the number . x + 17 > 26 x > 9
This </span>> is the greater than sign, we use this because it's no less than 26. Ideally we would use this sign: <span>http://etc.usf.edu/clipart/41700/41712/fc_greateq_41712_md.gif because it could be equal to 26.
</span><span>The number is <u>greater or equal to 9</u>
