Question

5-1-2х=3х+20+ х      4      6        3

Answer 1

3х+20/6+х/3-5-1-2х=0
потом приводим к общему знаменателю ОДЗ=24
получается 3х+20+х-5-1-2х=0 приводим подобные
2х-14=0
2х=14
х=7
Ответ:7

Answer 2

To solve the equation 5 - 1 - 2x = 3x + 20 + x, let's simplify both sides step by step:

5 - 1 - 2x = 3x + 20 + x

Combine like terms on each side:

4 - 2x = 4x + 20

Move the variables to one side and the constants to the other side:

-2x - 4x = 20 - 4

-6x = 16

Divide both sides of the equation by -6 to isolate x:

x = 16 / -6

Simplifying the right side:

x = -8/3

Therefore, the solution to the equation is x = -8/3 or approximately -2.67.
