Rachel can make 3 bracelets in an hour. Oliver can make only 2 bracelets in an hour, but he already has completed 5 bracelets. E
nignag [31]
Rachel: 3 bracelets in an hour.
Oliver: 2 bracelets in an hour but has completed 5 bracelets

Rachel : y = 3x
Oliver : y = 2x + 5

Let x be the number of hours. y is the total number of bracelets made in x hours.

3x = 2x + 5
3x - 2x = 5
x = 5

It would take 5 hours for Rachel to have the same number of bracelet as Oliver.

Rachel: 3x = 3(5) = 15
Oliver: 2x + 5 = 2(5) + 5 = 10 + 5 = 15
