525, I believe. Because each ticket is $5, and in total, the tickets were $105. So I multiplied 5 x 105=525. 

Please correct me if I'm wrong.

The equation that describes the number of people that went to the movies could be 5x = 105

What is a solution to a system of equations?

For a solution to be solution to a system, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs,

So solution to a system is the intersection of all its equation at single point(as we need common point, which is going to be intersection of course)(this can be one or many, or sometimes none)

Given; The cost of a movie ticket is $5. it costs a group of friends $105 to go to the movies.

Each ticket cost is $5,

The tickets were $105.

So, multiplied 5 x 105 = 525.

Let x be the number of people that went to the movies.

So, 105 / 5 = x = 21

OR

5x = 105

Therefore, the equation that describes the number of people that went to the movies could be 5x = 105
