Question
Student tickets for Oklahoma the cost of which is $5, and adult tickets cost $10. On Friday night, the drama department made $850. What equation would model this?
- 5x + 10y = 850
- 5x - 10y = 850
- x + y = 850
- 850y = 5x + 10
Hint:
An equation with the maximum order of 1 and an equation of a straight line is called the linear equation.
The correct answer is: 5x + 10y = 850
Student tickets for Oklahoma! cost = $5
adult tickets cost = $10
The drama department made = $850.
Equation = 5x + 10y = 850
The substitution method is the algebraic method to solve simultaneous linear equations.

In mathematics, the equation of a straight line describes the relationship between the coordinate points that comprise that line. It can be expressed in several ways and contains information about a line's slope, x-intercept, and y-intercept.
A straight line's standard form is given by the equation ax + by = c, where a, b, and c are real numbers. Let's illustrate how to put the equation y = 3x - 1 in standard form. Add 2x to neither side of the equation, and we get
y - 3x = 3x - 1 - 3x
= y - 3x = -1
= 3x - y = 1
As a result, we arrive at the line's standard form, which is 3x - y = 1
