Answer 1

Ответ:

Пошаговое объяснение:

3*2,1-1-2=3*2,1=6,3

6,3-(1+2)=3,3

Answer 2

1) (3×2-1)-2=5-2=3

2) (3×1-1)-2=2-2=0

Answer 3

To find the value of the expression |3x - 1| - 2 when x takes the values 2 and 1, we simply substitute these values into the expression and perform the calculations.

1. For x = 2: |3(2) - 1| - 2 |6 - 1| - 2 |5| - 2 5 - 2 3

So, when x = 2, the value of the expression is 3.

2. For x = 1: |3(1) - 1| - 2 |3 - 1| - 2 |2| - 2 2 - 2 0

So, when x = 1, the value of the expression is 0.

Therefore, the solutions for the given expression when x takes the values 2 and 1 are 3 and 0, respectively.
