Three red rods are 2 cm longer than two blue rods. Three blue rods are 2 cm longer
than four red rods. How long is each rod? The answer is blue equals 14 cm and red
equals 10 cm. Which system of equations must be solved?
3r - 2 = 2b
3b - 2 = 4r
3r = 2b - 2
3b = 4r - 2
3r + 2 = 2b
3b + 2 = 4r
3r + 2 > 2b
3b > 2 + 4r
