Answer 2

Ответ:

3(х+5)-(4-х)-(1+3)х-3=3х+15-4+х-х-3х-3=8

Answer 3

Let's simplify the expression step-by-step:

1. Distribute the coefficients inside the parentheses: 3(x+5) = 3x + 35 = 3x + 15 -(4-x) = -4 + x = x - 4 -(1+3)x = -(1x + 3x) = -x - 3

2. Now, combine like terms: 3x + 15 - (x - 4) - (-x - 3)

3. Remove the parentheses by changing the signs of the terms inside the second set of parentheses: 3x + 15 - x + 4 + x + 3

4. Combine like terms again: (3x - x + x) + (15 + 4 + 3)

5. Simplify the expression: 3x + 22

So, the simplified expression is 3x + 22.
