To solve the equation
Answer to Problem 10PPE
Explanation of Solution
Given:
Given equation
Concept Used:
- Least Common Denominator (LCD) is the smallest number that is divisible by the denominator of all the fractions that are being added or subtracted.
- Solving an equation containing rational expressions
- Multiply both sides of equations by LCD(least common denominator) of all denominators.
- Remove any grouping symbols and solve the resulting equation for the variable asked in equation
Calculation:
In order to solve the equation, observe that the LCD of all the denominators is
Thus, the solution of the given equation is
Now to check the solution, substitute
Thus, the solution of the given equation is
Now to check the solution, substitute
Thus, the solution is correct.
