7-29.

Write an equation in which *x* represents the time spent swimming and 2*x* represents the time spent playing volleyball.*x* + 2*x* = 4.5

Solve for the time spent swimming, *x*, then double that number to find the time spent playing volleyball.

3*x* = 4.5*x* = 1.5

1.5 hours spent swimming and 3 hours spent playing volleyball.
