Cycle paths inc, makes bicycles,tricycles,and unicycles. last week they made 88 more bicycles than unicycles, and 5 times as many tricycles as unicycles. if they made 40 more bicycles than tricycles, how many unicycles did they make
Let's name variables: x = bicycles y = tricycles z = unicycles We write the following system of equations: x = 88 + z y = 5z x = 40 + y We solve the equation system for z: 1) x = 40 + y 2) y = 5z 3) x = 88 + z Substituting x and y in equation 1: 88 + z = 40 + 5z We cleared z: 4z = 88-40 z = 48/4 z = 12 Answer: They did make 12 unicycles
