Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible: 48 - (6 • x) 48 - 6x Now, on the left hand side, the x cancels out the denominator, while, on the right hand side, zero times anything is still zero. Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator Adding fractions that have a common denominator : Equivalent fraction : The fraction thus generated looks different but has the same value as the whole Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

Step by step solution :
