Bobby's Bike Shack orders tires each week for its two-wheel bikes and three-wheel bikes. They order tires for all 47 of their bikes this week. If they ordered 112 tires, how many two-wheel bikes does the Bike Shack have?
For this question, I am required to show my work so please explain your answer.
x = number of two wheel bikes
2x = bike tires for two wheelers
47 - x = three wheel bikes
3(47-x) = tires for three wheelers
2x + 3 (47-x) = 112 solve for x (the number of two wheel bikes)
