5-104.

Define the variables. Write the equations for the populations of the schools over time in *y* = *mx* + *b* form.

The equation that represents the population of Tehachapi High School over time is *y* = 34*x* + 839, because the growth is 34 students (*m*) and it started at 834 students (*b*). Now write the equation for Fresno High.

Once you have both equations you have a system of equations. So solve by using the Equal Values method.
