how will i solve if there is 2 variables?

(Subtraction of RationalAlgebraic Expressions)
5 - xy 14 + 8xy
------- - -------- = ?
9z 9z

To solve the given expression, you need to follow these steps:

Step 1: Find a common denominator for the two fractions (expressions) in the equation. In this case, the common denominator is 9z, as it is present in both fractions.

Step 2: Rewrite the fractions with the common denominator:

(5 - xy)/(9z) - (14 + 8xy)/(9z)

Step 3: Simplify each fraction individually:

First fraction: (5 - xy)/(9z)

Second fraction: (14 + 8xy)/(9z)

Step 4: Combine the fractions with the common denominator:

(5 - xy - (14 + 8xy))/(9z)

Step 5: Simplify the expression within the parentheses:

5 - xy - 14 - 8xy

Combine like terms:

-xy - 8xy + 5 - 14

Simplify further:

-9xy - 9

Thus, the simplified expression is -9xy - 9.
