Solving a System of Linear Equations in Three Variables
A linear equation in one variable is an equation which can be written in the form: ax + b = c for a, b, and c real numbers with a 0. Linear equations in one variable: 2x + 3 = 11 2(x 1) = 8 Not linear equations in one variable: 2x + 3y = 11 Two variables can be rewritten 2x + ( 2) = 8. x is squared. Variable in the denominator (x 1)2 = 8 5 7 3 2
You would remember that equations use the equality (=) sign; it is missing in expressions. Of these given expressions, many have more than one variable. For example, 2 xy + 5 has two variables. We however, restrict to expressions with only one variable when we form equations. Moreover, the expressions we use to form equations are linear. This means
