Question

срочно!!! помогите решить

Answer 1

Пошаговое объяснение:

1. 1)13х-26 = -130

13х = -130+26

13х = -104

х = -104 ÷ 13

х = -8

2)5х-3 = 3х-11

5х-3х = -11+3

2х = -8

х = -8 ÷ 2

х = -4

3)24 (х+2) = 6 (х-4)

24х+48 = 6х - 24

24х-6х = -24-48

18х = -72

х = -72÷18

х = -4

\ - дроб

4) (2\3)х+1 = (1\2)х+(1\6)

(2\3)х - (1\2)х = (1\6) - 1

(4-3\6)х = -(5\6)

х = -(5\6)÷(1\6)

х = -(5\6)×(6\1)

х = -5
