In order to make 1 bike it requires 1 horn, 2 tires, and 1 chain. What would be the coefficients for the horn, tire, and chain, assuming you wanted to make 4 bikes? Write the coefficients below!

Bike is B

Horn is H

Tire is T

Chain is C

Explanation:

one bike would be B = H + 2T + C

you would have to multiply both sides by 4 to make 4 bikes, so then it would be

4B = 4H + 8T + 4C
