There are more than two methods, and of these, matrix inversion is probably the easiest for solving systems of linear equations in several unknowns.
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no single solution. The solution is in the form of the line whose equation is 8x-y2-2 = 0
There are 2 unknowns
lesson 2 on problem solving. what are common methods for establishing a benchmark?
x + y + x = 2x + y
The alphabet so 26+2 because of the ? and the ! unknowns.
It is a linear equation in two variables, x and y. It can be considered an equation of a straight line in 2 dimensions (or a plane in 3 dimensions, or a k-brane in k+1 dimensions). It cannot be solved for x or y since solving equations in two unknowns requires two independent equations.
The answer is....... 1. read the problem 2. determine the unknowns and represent them 3. write an equation 4. solve the equation 5. answer the question
Sorry, but it is impossible to solve this equation by itself. Since you have two unknowns, you need two equation.
Step 1: Determine your known variablesStep 2: Determine your unknown variablesStep 3: Determine the relationship (equations, etc.) between the two sets of variablesStep 4: Solve for any and all unknowns using any techniques you know
If A is number of adult tickets, and B is number of student tickets, we get a system of two equations for two unknowns: 4A+2B=2446 A+B=920 By solving this system, we obtain B=617
