LINEAR EQUATION - Solve for x in the following equation.

Example 1: tex2html_wrap_inline74

Add tex2html_wrap_inline76 to both sides of the equation: tex2html_wrap_inline78

Divide both sides by tex2html_wrap_inline82

The answer is tex2html_wrap_inline84

Check the solution by substituting tex2html_wrap_inline86 or 2.80588370148 in the original equation for x. If the left side of the equation equals the right side of the equation after the substitution, you have found the correct answer.
