Answer 2

It looks like you have an expression with various terms involving the variable "у." To simplify this expression, let's break it down step by step:

7у - 5/10у - 10у - 9/5у + 10 - 5у/у

Step 1: Combine like terms Combine the "у" terms and the constant terms separately:

(7у - 10у - 10у) + (10 - 5/10у - 9/5у - 5у/у)

Step 2: Combine the "у" terms Combine the "у" terms in the first set of parentheses:

(-13у) + (10 - 5/10у - 9/5у - 5у/у)

Step 3: Simplify the constant terms Combine the constant terms in the second set of parentheses:

-13у + (10 - 5/10у - 9/5у - 5у/у)

Step 4: Simplify the fractions To simplify the fractions, find a common denominator, which in this case is 10у. Rewrite the fractions with the common denominator:

-13у + (10 - (5у/10у) - (9/5y) - (5у/у))

Now, perform the calculations:

-13у + (10 - 1/2 - 9/5 - 5)

Step 5: Continue simplifying Now, simplify the expression by subtracting the fractions and the constant:

-13у + (10 - 1/2 - 9/5 - 5) -13у + (10 - 10/20 - 18/20 - 100/20)

-13у + (10 - 28/20)

-13у + (10 - 7/5)

Step 6: Subtract the constant

To subtract the constant from the expression, you can think of it as having a common denominator of 5:

-13у + (50/5 - 7/5)

Now, subtract the constants:

-13у + (43/5)

Step 7: Combine the terms

Combine the terms to get the simplified expression:

-13у + 43/5

So, the simplified expression is:

-13у + 43/5
