Examples: 3(x - 3) = 2x + 5. is a linear equation since when we multiply out the left side we get the equation 3x - 9 = 2x + 5. 3/x + 4 = 5 is not a linear equation. since the term 3/x is the same as 3x-1, a term with power other than 1. Method To Solve Linear Equations: To solve linear equations, remember to do the following:

Does the equation have a single variable with no exponents? If yes, then it is a linear equation. To solve it, isolate the variable on one side of the equation and move all constants to the other side of the equation. Examples: Solve each equation for x: Does the equation have a single variable that is always raised to the same power?

This allows us to write the equation: Example 6. If is a linear function, , and , find an equation for the function. In example 3, we computed the rate of change to be . In this case, we do not know the initial value, so we will have to solve for it. Using the rate of change, we know the equation will have the form.
