Question

7 + 2x > 5 + x,3x + 2 < 8+x​

Answer 1

Ответ:

Пошаговое объяснение:

7 + 2x > 5 + x

2x - x > 5 - 7

x > -2

3x + 2 < 8 + x​

3x - x < 8 - 2

2x < 6

x < 6 ÷ 2

x < 3

Answer 2

To solve these inequalities, let's work on them one by one:

1. 7 + 2x > 5 + x

Let's simplify the equation: Subtract x from both sides: 7 + x > 5 Subtract 7 from both sides: x > -2

So, the solution for this inequality is x > -2.

2. 3x + 2 < 8 + x

Let's simplify the equation: Subtract x from both sides: 3x - x < 8 - 2 Simplify further: 2x < 6 Divide both sides by 2: x < 3

So, the solution for this inequality is x < 3.

Therefore, the solution to the system of inequalities is x > -2 and x < 3.
