When Makayla moved into a new house, she planted two trees in her backyard. At the time of planting, Tree A was 19 inches tall and Tree B was 35 inches tall. Each year thereafter, Tree A grew by 6 inches per year and Tree B grew by 2 inches per year. Let A represent the height of Tree A t years after being planted and let B represent the height of Tree B t years after being planted. Write an equation for each situation, in terms of t, and determine the number of years after the trees were planted when both trees have an equal height. (help ASP)
