Chapter 7: Q. 132 (page 668)

In the following exercises, perform indicated operations.
$\frac{8 y - 4}{5 y + 2} - 6$

Short Answer

Expert verified

The resultant expression is $\frac{- 22 y + 8}{5 y + 2}$ .

Step by step solution

Step 1. GIven Information

The given expression is $\frac{8 y - 4}{5 y + 2} - 6$ .

Step 2. Express with LCD

The LCD of the given terms is $5 y + 2$ .
Express the given expression with the LCD.

$\frac{8 y - 4}{5 y + 2} - 6 = \frac{8 y - 4}{5 y + 2} - \frac{30 y - 12}{5 y + 2}$

Step 3. Simplify

As the denominator is the same for both the terms, perform subtraction in the numerator and place it over the common denominator.

$\frac{8 y - 4 - 30 y + 12}{5 y + 2} = \frac{- 22 y + 8}{5 y + 2}$

So, the resultant expression is $\frac{- 22 y + 8}{5 y + 2}$ .
