Question

-2 <= 1 + 3*x 1 + 3*x <= 4

Answer 1

Ответ:

x => - 1 ; x <= 1

Объяснение:

- 2 <= 1 + 3x

- 2 - 1 <= 3x

- 3 <= 3x

3x => - 3

x => - 1

1 + 3x <= 4

3x <= 4 - 1

3x <= 3

x <= 1

Answer 2

The inequalities you've provided are a system of linear inequalities involving the variable 'x'. Let's solve this system step by step:

1. -2 <= 1 + 3*x: Subtract 1 from both sides to isolate the term with 'x':

   -2 - 1 <= 3x -3 <= 3x

   Divide both sides by 3:

   -1 <= x

2. 1 + 3*x <= 4: Subtract 1 from both sides to isolate the term with 'x':

   3x <= 4 - 1 3x <= 3

   Divide both sides by 3:

   x <= 1

So, from the first inequality, we have -1 <= x, and from the second inequality, we have x <= 1.

Combining these results, we can say that the solution for 'x' lies in the range -1 <= x <= 1. This means that any value of 'x' within this range will satisfy both inequalities simultaneously.
