SOLVING LINEAR EQUATIONS

Recall the following:


LINEAR EQUATION - Solve for x in the following equation.

Problem 7c: tex2html_wrap_inline112

eqnarray41

The exact answer is tex2html_wrap_inline114

The approximate answer is tex2html_wrap_inline116

tex2html_wrap_inline118

Check the solution by substituting tex2html_wrap_inline120 or 143.418948 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 143.418948 is substituted for x, the solution x=143.418948 is verified.
