X-4 in word form
Please help it’s due today!

This is the "less than" construction, which is backward in the math from the English. They've given me some unknown quantity, x, and they're telling me that they want the expression which stands for the quantity that is four units smaller than x. To find this quantity, I'll need to subtract the four from the unknown. This translates to:

x – 4

To be clear, "four less than (the unknown)" in English means "(the unknown), less four" in algebra. If you're not sure of this, plug numbers in. If you get four dollars less an hour than (an unknown worker), you wouldn't subtract that worker's pay from 4; instead, you'd subtract 4 from that worker's pay: p – 4. Use this same order in your algebraic expression.
