Desiree answered 40 questions correctly

Step-by-step explanation:

Let

x =  number of questions answered correctly

y = number of questions unanswered

z = number of wrong answers unanswered

The system of equations can be expressed

x + y + z = 50

3*x  - 0.5*y -1*z = 110

Desiree did not leave any question unanswered

This means that the equations become

y = 0

x + z = 50

3*x -z = 110

If we add them together, we get

4x = 160

x = 40

z = 10
