решыте уравнение срочно!!!! ​

Answer 1

Ответ:

№1:

х-2/3=2 1/3

х-2/3=7/3

х=7/3+2/3

х=3

№2:

3(2х-1)-4=5х+26

6х-3-4=5х+26

6х-7=5х+26

6х-7-5х=26

6х-5х=26+7

х=26+7

х=33

Answer 2

$x - \frac{2}{3} = 2 \frac{1}{3} \\ \\ x - \frac{2}{3} = \frac{7}{3} \\ \\ x = \frac{7}{3} + \frac{2}{ 3} \\ \\ x = 3$

$= = = = = = = = = = = = = = = = = = = = = = = \\ 3(2x - 1) - 4 = 5x + 26 \\ \\ 6x - 3 - 4 = 5x + 26 \\ \\ 6x - 7 = 5x + 26 \\ \\ 6x - 7 - 5x =26 \\ \\ 6x - 5x = 26 + 7 \\ \\ x = 26 + 7 \\ \\ x = 33$
