Question

6-3х>0 5х-3 >0, 2х-1>0 15-3х>0

Answer 1

Ответ:

3(2 1/2х-0,2)-15 1/15=6-(2/3-0,5х)

7,5х-0,6-15 1/15=6-2/3+0,5х

7х=5 1/3+15 1/15+3/5

7х=21,

х=21:7

х=3

Answer 2

To solve the inequalities, let's solve them one by one:

1. 6 - 3x > 0: Subtract 6 from both sides: -3x > -6 Divide by -3 (note that we are dividing by a negative number, so we need to reverse the inequality symbol): x < 2

2. 5x - 3 > 0: Add 3 to both sides: 5x > 3 Divide by 5: x > 3/5

3. 2x - 1 > 0: Add 1 to both sides: 2x > 1 Divide by 2: x > 1/2

4. 15 - 3x > 0: Subtract 15 from both sides: -3x > -15 Divide by -3 (remember to reverse the inequality symbol): x < 5

So, the solutions to the given inequalities are: x < 2, x > 3/5, x > 1/2, x < 5
