Question

subtract.
$-dfrac{2b - 2y}{2b}-dfrac{2b + 9y}{2b}$
simplify your answer as much as possible.

Explanation:

Step1: Combine fractions (common denominator)

$\frac{-(2b-2y) - (2b+9y)}{2b}$

Step2: Distribute negative signs

$\frac{-2b + 2y - 2b - 9y}{2b}$

Step3: Combine like terms

$\frac{(-2b-2b) + (2y-9y)}{2b} = \frac{-4b -7y}{2b}$

Step4: Split the fraction (optional simplification)

$\frac{-4b}{2b} + \frac{-7y}{2b} = -2 - \frac{7y}{2b}$

Answer:

$\frac{-4b -7y}{2b}$ or $-2 - \frac{7y}{2b}$
