Question

Rachel can make 3 bracelets in an hour. Oliver can make only 2 bracelets in an hour, but he already has 5 completed bracelets. Explain to Rachel how she can use a system of equations to determine when she will have the same number of bracelets as Oliver.

Answer 1

We suppose the hours taken is x. So after x hours, Rachel can have 3x bracelets. And Oliver can have 5+2x bracelets. When they have the same number of bracelets, the equation is 3x=5+2x. x=5.
