9-66.

Linda takes $2$ hours more than Greg does to service a photocopier. Together they can service the copier in $5$ hours. How long does each person take to service the copier on his or her own?

$\text{(Greg's rate)(time) + (Linda's rate)(time) = 1} \text{ copier}$

The time is $5$ hours. Express each person's rate in copiers per hour when writing your equation.

$\frac{1}{x}(5)+\frac{1}{x+2}(5)=1$
