Answer 2

1.3(а-1.7)=3а-5,1
2.-3(1.6+у)=-4.8-3у

Answer 3

Solving the Equation

To solve the given equation 3(a-1,7)+2)-3(1,6+y), we can follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

First, let's simplify the expression step by step:

1. 3(a-1,7)+2): - We need to distribute the 3 to both terms inside the parentheses: - 3 * a = 3a - 3 * (-1,7) = -5,1 - So, this simplifies to 3a - 5,1 + 2.

2. -3(1,6+y): - Again, we need to distribute the -3 to both terms inside the parentheses: - -3 * 1,6 = -4,8 - -3 * y = -3y - So, this simplifies to -4,8 - 3y.

Now, we can combine the simplified expressions: - 3a - 5,1 + 2 - 4,8 - 3y.

Final Simplified Expression

Combining the terms, the simplified expression is: - 3a - 5,1 - 4,8 + 2 - 3y.

This is the simplified form of the given expression 3(a-1,7)+2)-3(1,6+y).
