The total number of slices of pizza eaten by the runner up is 3.5 slices

How to write and solve equation

let

x = number of slices of pizza eaten by the runner up

  • Davonne ate four more than twice as many slices as the runner up.

Number of pizza eaten by Davonne = 2x + 4

Davonne = 11 slices

Equates

2x + 4 = 11

  • subtract 4 from both sides

2x = 11 - 4

2x = 7

  • divide both sides by 2

x = 7/2

x = 3.5 slices

Therefore, the number of slices of pizza eaten by the runner up is 3.5 slices
