Recall the following:

LINEAR EQUATION - Solve for x in the following equation.

Problem 1.5c:


Get rid of the denominators by multiplying both sides by 12, the smallest number that 2,3, and 4 will divide into evenly.

Recall the line that separates the numerator and the denominator also functions as a parenthesis. It instructs the reader to treat the numerator as one number and the denominator as one number.







Subtract 48x from both sides of the equation and add 1 to both sides of the equation:


Divide both sides by 8:


The answer is tex2html_wrap_inline169 .

Check the solution by substituting tex2html_wrap_inline171 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 after you substitute tex2html_wrap_inline169 , the answer tex2html_wrap_inline169 You can also check the answer with your calculator:


You can also check your answer by graphing tex2html_wrap_inline181 (left side of the original equation minus the right side of the original equation). The x-intercept is 0.875.
