Question

Решите уравнение
4х-3=2х+1
___. ___
5..........2

Answer 1

$\frac{4x - 3}{5} = \frac{2x + 1}{2} \\ 4x - \frac{1}{5} = 2x + \frac{0}{5} \\ 4x - 2x = \frac{0}{5} + \frac{1}{5} \\ 2x = 2 \\ x = 1$

Answer 2

4х-3=2х+1
(4х-2х)-3=(2х-2х)+1
2х-3=1
2х+(3-3)=1+3
2х=4
2х    4
--- = -
2     2
    4
х=--
