    Answer:

    Points = 17\ Points

    Points = (20 - x)\ points

    Step-by-step explanation:

    Given

    Questions = 20

    Points = 1

    Solving (a): 3 questions wrong

    First, we need to determine the total possible points

    Total = Questions * Points

    Total = 20 * 1\ point

    Total = 20\ points — (1)

    Next, is to determine the points of 3 questions

    3\ Questions = 3 * 1\ Point

    3\ Questions = 3\ Points — (2)

    Subtract (2) from (1)

    Points = 20 - 3

    Points = 17\ Points

    Her test score is 17 points

    Solving (b): x questions wrong

    x\ questions = x * 1\ point

    x\ questions = x\ points — (3)

    Subtract (3) from (1)

    Points = (20 - x)\ points

    Her points would be 20 – x points
