Marcia can write an expression for the number of candles she will have at the end of "h" hours. She can also write an expression for the number of candles Kevin will have at the end of "h" hours. She can set the two expressions equal to each other and solve for "h", the number of hours until each has the same number of candles.
<span>5h = 4h+7 </span>
<span>h = 7 … subtract 4h from each side </span>
<span>In 7 hours, each will have the same number of candles.</span>
