Answer 3

To solve the inequality 2x + 5 > 7x - 10, follow these steps:

Step 1: Move all the x terms to one side of the inequality and the constant terms to the other side.

2x + 5 > 7x - 10

Subtract 2x from both sides:

2x - 2x + 5 > 7x - 2x - 10

This simplifies to:

5 > 5x - 10

Step 2: Move the constant term to the other side of the inequality.

Add 10 to both sides:

5 + 10 > 5x - 10 + 10

This simplifies to:

15 > 5x

Step 3: Divide by the coefficient of x to isolate x.

Divide both sides by 5:

15 / 5 > 5x / 5

This simplifies to:

3 > x

So the solution to the inequality is:

x < 3
