SOLVING LINEAR EQUATIONS

Recall the following:


LINEAR EQUATION - Solve for x in the following equation.

Problem 7a: tex2html_wrap_inline89

eqnarray38

The answer is tex2html_wrap_inline91

Check the solution by substituting tex2html_wrap_inline93 or 17.337252 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.

Since the left side of the original equation equals the right side of the original equation when the value 17.337252 is substituted for x, the solution x = 17.337252 is verified.
