Question 188321
<font face="Goudy Old Style" size="+2">


Games won by Broncos: <i>x</i>


Games won by Cowboys: 2.5<i>x</i>


Games won by both:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  2.5x + x = 7]


Solve for <i>x</i>, then subtract that value from 7.


You could actually go at this directly and save the subtraction step at the end if you said:


Games won by Cowboys: <i>x</i>


Games won by Broncos: *[tex \Large \frac{x}{2.5}]


Games won by both:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  \frac{x}{2.5} + x = 7]


But that is a messier equation to solve.
