Answer 1

Ответ:

12.3-8(2у-0.6)+(5у-6)=12.3-16у+4.8+5у-6=11.1-11у

Answer 2

To simplify the expression 12,3 - 8(2y - 0,6) + (5y - 6), we can follow the order of operations (PEMDAS/BODMAS) to evaluate it step by step:

Step 1: Simplify within parentheses: -8(2y - 0,6) can be simplified to -16y + 4.8.

The expression now becomes: 12,3 - 16y + 4.8 + (5y - 6).

Step 2: Combine like terms: Combine the constant terms 12,3 and 4.8 to get 17.1.

The expression now becomes: 17.1 - 16y + (5y - 6).

Step 3: Simplify within parentheses: (5y - 6) remains as it is.

The expression now becomes: 17.1 - 16y + 5y - 6.

Step 4: Combine like terms: Combine the y terms -16y and 5y to get -11y.

The expression now becomes: 17.1 - 11y - 6.

Step 5: Simplify the constant terms: Combine the constant terms 17.1 and -6 to get 11.1.

The final simplified expression is: 11.1 - 11y.
