Question:

Johnathan went to the store to buys pants and socks. Johnathan bought a pair of pants for \$42 dollars. This is 14 less than twice what he spend on his socks. How much were the socks?

Courtney W.

So, lets make the variable p represent the price of the pants and the variable s represent the price of the socks. This makes p=42 and p=2s-14. Simply plug in the known variable p into the second equation to solve for s, the price of the socks. 42=2s-14, add 14 to both sides. 56=2s, divide each side by 2 to isolate the variable. 28=s s=\$28 The price of the socks was \$28.
