Question

решить уравнения
х+(4+x)+х=16
(12х-24)=3х
-5х+35=-(-3х+12)+27
3х+(4х-6)=8-(7х-14)​

Answer 1

Ответ:

Пошаговое объяснение:

х+(4+x)+х=16

3x + 4 = 16

3x = 12

x = 4

(12х-24)=3х

12x - 3x = 24

9x = 24

x = 24/9

-5х+35=-(-3х+12)+27

-5x - 3x = -35 - 12 +27

8x = 20

x = 20/8

3х+(4х-6)=8-(7х-14)​

3x + 4x + 7x = 6 + 14

14x = 20

x = 20/14
