Linear relationships can be expressed in a graphical format where the variable and the constant are connected via a straight line or in a mathematical format where the independent variable is multiplied by the slope coefficient, added by a constant, which determines the dependent variable.
Answer:
If a = the number of adult tickets sold, then (a + 20) = the number of student tickets sold

2a = 220
a = 110
There were 110 adult and 110 + 20 = 130 student tickets sold
