c plus m equals eighteen; two c plus two m equals sixty-six

c plus m equals eighteen; four c plus two m equals sixty-six

c plus m equals sixty-six; four c plus two m equals eighteen

two c plus two m equals eighteen; c plus m equals sixty-six

c + m = 18 (because this is the total number of vehichles)
4c + 2m = 66 (because there are 4 wheels on a car, 2 wheels on a motorcycle)
