Answer 2

To simplify the given expression, let's break it down step by step:

0,3(6 - 3y) - 4,5 - 0,8(y - 9)

Step 1: Distribute the 0.3 to the terms inside the parentheses:

0.3 * 6 - 0.3 * 3y - 4.5 - 0.8(y - 9)

Step 2: Simplify the multiplications:

1.8 - 0.9y - 4.5 - 0.8(y - 9)

Step 3: Distribute the -0.8 to the terms inside the parentheses:

1.8 - 0.9y - 4.5 - 0.8y + 7.2

Step 4: Combine like terms:

(1.8 - 4.5 + 7.2) - 0.9y - 0.8y

Step 5: Simplify within the parentheses:

4.5 - 0.9y - 0.8y

Step 6: Combine like terms:

(4.5 - 0.9y - 0.8y)

Step 7: Simplify the subtraction:

(4.5 - 1.7y)

Therefore, the simplified expression is 4.5 - 1.7y.
