Ariel and Sarah are each growing a plant. The equation y = 3x + 10 can be used to model the height, y, in centimeters (cm), of Ariel’s plant after x weeks. The equation y = 4x + 3 can be used to model the height, y, in cm, of Sarah’s plant after x weeks. After how many weeks will Ariel’s and Sarah’s plants be the same height, and what will that height be?
