Answer 1

Объяснение:

$7x - (5x - (3x + y)) = 7x - (5x - 3x - y) = 7x - (2x - y) = 7x - 2x + y = 5x + y$

Answer 2

Solving the Expression: 7x - (5x - (3x + у))

To solve the expression 7x - (5x - (3x + у)), we need to apply the distributive property and simplify the expression step by step.

1. Start by simplifying the innermost parentheses, which is (3x + у): - The expression inside the parentheses is 3x + у.

2. Next, distribute the negative sign to the terms inside the second set of parentheses: - Distributing the negative sign, we get -5x + (-3x - у).

3. Now, substitute the simplified expression from step 1 into the second set of parentheses: - The expression becomes -5x + (3x + у).

4. Finally, substitute the simplified expression from step 3 into the outermost set of parentheses: - The expression becomes 7x - (-5x + (3x + у)).

To simplify further, we can remove the parentheses and combine like terms:

7x - (-5x + 3x + у) = 7x + 5x - 3x - у = (7x + 5x - 3x) - у = 9x - у

Therefore, the simplified expression is 9x - у.
