SOLVING LINEAR EQUATIONS

Recall the following:


LINEAR EQUATION - Solve for x in the following equation.

Problem 7b: tex2html_wrap_inline86

eqnarray40

The exact answer is tex2html_wrap_inline88 The approximate answer is tex2html_wrap_inline90

Check the solution by substituting tex2html_wrap_inline92 or -1.848612 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 -1.848612 is substituted for x, the solution x=-1.848612 is verified.
