CSEC Mathematics · May/June 2016 · Paper 2 · Question 3(a)(i)

A Venn diagram shows the number of students studying History (H) and French (F) in a class of 30 students. The diagram shows 18-x students in H only, x students in H and F, 14-x students in F only, and 5 students outside both sets. U represents the set of all students.

Write an expression, in x, in its simplest form, for the TOTAL number of students in the class.

The mark scheme is shown once you've answered.
