21 cars, 32 motorcycles.create a system of equations using x for cars and y for motorcycles.
multiply the top equation by 2 to prepare for elimination method
subtract terms
divide both sides by negative 2 to solve for x
x =21
plug in x into original equation to solve for y.
21 + y = 53
subtract both sides by 21
y=32
