On a quiz show, Linda won $10 less than three times as much as Charlie. If Linda won $800, how much did Charlie win?
PilotLPTM [1.2K]

Using a system of equations, it is found that Charlie won $270.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable x: Amount earned by Linda.
  • Variable y: Amount earned by Charlie.

Linda won $10 less than three times as much as Charlie, hence:

x = 3y - 10

Linda won $800, hence the amount won by Charlie is found as follows:

800 = 3y - 10

3y = 810

y = 810/3

y = 270
