Explain why the steps for solving equations are usually given as removing grouping symbols first, even though it is not necessarily the only way to solve. for example, the equation 2(x + 3) = 16 could be solved by dividing the equation through by 2 to get x + 3 = 8.

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
