Can someone please help me understand this problem? "A biologist is comparing the growth of a population of flies per week to the number of flies a lizard will consume per week. She has devised an equation to solve for which day (x) the lizard would be able to eat the entire population. The equation is 3x = 5x - 1. However, she has observed that the lizard cannot eat more than seven flies in one week."
