Question

1) 20x — 11 > 19x + 18 и 13х – 2 > 12х + 27;​

Answer 1

1) 20x — 11 > 19x + 18 и 13х – 2 > 12х + 27;

х=29

Answer 2

To solve the inequalities:

1. 20x - 11 > 19x + 18
2. 13x - 2 > 12x + 27

You can start by isolating the variable x on one side of the inequality sign in each equation.

1. 20x - 11 > 19x + 18

Subtract 19x from both sides:

20x - 19x - 11 > 18

x - 11 > 18

Now, add 11 to both sides:

x - 11 + 11 > 18 + 11

x > 29

So, the solution to the first inequality is x > 29.

2. 13x - 2 > 12x + 27

Subtract 12x from both sides:

13x - 12x - 2 > 27

x - 2 > 27

Now, add 2 to both sides:

x - 2 + 2 > 27 + 2

x > 29

So, the solution to the second inequality is also x > 29.

Therefore, the solution to the system of inequalities is:

x > 29 (for both inequalities).
