# Example of solving a fraction equation

Step 1: think about how to remove denominators of the fraction equation. find the factors can be used to remove the denominators of the fraction equation. Step 2: both sides of the equation multiply the factors to remove denominators. When the numerator and denominator have the common factor, the factor can be removed. Step 3: when multiply polynomial, pay attention on the order and sign. Step 4: keep all variables in the left side of the equation and move all numbers to the right side of the equation. when move an item cross the 'equal' sign, the item should change its sign (which is equal to adding an item on both sides of the equation). Step 4: divide the coefficient on the both sides of the equation to get the value of the variable. Step 5: check if the answer is correct by substitute the value into the equation to see if the left side of the equation is equal to the right side of the equation. If yes, then the value is the answer.
