Question

2x- 4>7x-1 неравенство

Answer 1

2х-4>7x-1

-5x>3

5x<-3

x<-3/5

(-безконечности до -3/5)

Answer 2

To solve the inequality 2x - 4 > 7x - 1, you need to isolate the variable x on one side of the inequality sign. Here's how you can do it:

1. Move all the x terms to one side of the inequality and the constant terms to the other side. You can do this by adding 1 to both sides and subtracting 2x from both sides: 2x - 2x - 4 + 1 > 7x - 2x - 1 + 1

Simplifying: -4 + 1 > 5x

2. Combine the constant terms: -3 > 5x

3. Finally, divide both sides by 5 (remember that when dividing or multiplying an inequality by a negative number, you need to reverse the inequality sign): -3/5 < x

So the solution to the inequality is: x > -3/5
