x+y <= 95
y >= x+20
An exam consists of two parts, Section X and Section Y. There can be a maximum of 95 questions. There must be at least 20 more questions in Section Y than in Section X. Write a system of inequalities to model the number of questions in each of the two sections. Then solve the system by graphing.
