Timothy planted two trees in his front yard. The first tree is 2 feet tall, and is growing at a rate of 1.7 feet each year. The second tree is 3.5 feet tall, and is growing at a rate of 0.8 feet each year. Which equation can be used to find y, the number of years until both trees are the same height?

• 1.7y − 2 = 3.5 − 0.8

• 2y + 1.7 = 3.5y + 0.8

• 2y + 1.7 = 0.8y + 3.5

• 1.7y + 2 = 0.8y + 3.5
