Ticket Sales and Linear Equations

This video tutorial explains how to solve an application problem using the general form of a linear equation. It begins with a review of the standard form of linear equations and then sets up a problem involving ticket sales. The tutorial defines variables for adult and children's tickets, formulates an equation to represent total sales, and solves for the number of children's tickets sold. The process involves substituting known values and solving a two-step equation.

What is the general form of a linear equation?

• a + b = c

• ax + by = c

• ax^2 + bx + c = 0

• a/b = c
