Where would the like term be in this: Gavin’s goal is to bike 65 miles in four days. The expression representing the total distance he should bike in four days is x + 1.5x + 2.25x + 3.375x.

His goal and the distance he should bike over the four days must be equal. So the equation is 65 = x + 1.5x + 2.25x + 3.375x. This equation can be used to find the number of miles Gavin should bike on the first day, x.
