Recall the following:
LINEAR EQUATION - Solve for x in the following equation.
Get rid of the denominators by multiplying both sides by 35, the smallest number that 7, and 5 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 30x from both sides of the equation and subtract 19 from both sides of the equation:
Divide both sides by 44:
The answer is x=4.
Check the solution by substituting 4 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.
