So, my conclusion remains that Equations 3 and 4 by themselves constitute 2 independent scalar equations in 3 scalar unknowns (F2, F2, Fs), assuming all the angles are known. HOWEVER, assuming there is a solution, I agree with you there must be redundancy somewhere among the 6 equations. Solving linear equations is much more fun with a two pan balance, some mystery bags and a bunch of jelly beans. Algebra tiles are used by many teachers to help students understand a variety of algebra topics. And there is nothing like a set of co-ordinate axes to solve systems of linear equations.

When solving linear equations, the goal is to isolate the unknown (variable) to find its value. This is accomplished by adding, subtracting, multiplying, or dividing. Let’s start with a simple example: x + 4 = 9. The main rule to keep in mind when trying to isolate a variable is that you always have to keep the equation balanced.

The ultimate goal of solving a system of linear equations is to find the values of the unknown variables. Here is an example of a system of linear equations with two unknown variables, x and y: Equation 1: 4x + 3y = 20 -5x + 9y = 26 To solve the above system of linear equations, we need to find the values of the x and y variables. There are ... In this module we will only be concerned with equations in one unknown, not involving squares, higher powers, and so on; such equations are called linear equations. Once we have solved an equation, we can always check that our solution is, in fact, correct. This is important, since in later work, the methods of solution may produce There are two ways to solve a system of linear equations that I know of. 1. Rearrange one equation to retain only one variable on the left side. Substitute the equation on the right side in for the variable in another equation.
