The question you posted doesn't really show the question. Are there any words like how, when, where.... and do you have answer choices? : ) maybe then I can help?
Let a and c represent the numbers of adult and children's tickets sold, respectively. The system of equations will have one equation for revenue and one equation for number of tickets.
The revenue equation is
18a +9c = 4959
The number of tickets equation is
a + c = 319
_____
The solution can be found any number of ways. It is
(a, c) = (232, 87)

Answer:
-3.75 or -3 3/4
Step-by-step explanation:
The first step in solving a problem is illustrating it just as what the picture shows. The ladder represents the hypotenuse, or the longest side of the right triangle. It measures 14 feet. The base measures 6 feet. The height of the top of the ladder from the base of the wall is denoted as x. Since this is a right triangle, the special equations for Pythagorean theorems would apply. The equation is
c^2 = a^2 + b^2, where c is the hypotenuse, a and b are the other shorter legs. Substituting the values,
14^2 = 6^2 + x^2
x^2 = 14^2 - 6^2
x^2 = 160
x = 4√10 = 12.65 feet
