Answer 3

I can help you with your math problem. Here is the detailed solution:

2(х-2)-1=5(х-2)-7

Expand the brackets:

2x - 4 - 1 = 5x - 10 - 7

Simplify by collecting like terms:

2x - 5 = 5x - 17

Subtract 2x from both sides:

-5 = 3x - 17

Add 17 to both sides:

12 = 3x

Divide both sides by 3:

4 = x

The answer is x = 4.Ответь+подробно.+2(х-2)-1=5(х-2)-7+Помогите+плиз
