At a pizza eating competition, Davonne ate four more than twice as many slices as the runner up. If Davonne ate 11 slices, then how many slices did the runner up eat?

Let's begin with x as the number of slices the runner up ate.

Davonne ate four more than twice

So the equation should look somewhat like this.

4+2x=11

2x=7

x=3.5

So the runner up ate 3.5 slices

Davonne ate four more than twice as many slices as the runner up. If Davonne ate 11 slices, then how many slices did the runner up eat?
