Question

6x + 18 = 0
3(5-x) =11 + 2x
2x + 3 = 3x -2
Помогите решить

Answer 1

1)x=-3
2)x =0,75 4-3x=0
3)x=5 -x+5=0

Answer 2

6x + 18 = 0

6x = 0 - 18 = -18

6x= -18 : 6

x = -3

-----------------------

3(5-x) = 11 + 2x

15 - 3x = 11 + 2x

-3x -2x = 11 - 15

-5x = -4

x = -4 : (-5)

x = 0.8

----------------------

2x + 3 = 3x - 2

2x - 3x = -2 - 3

-x = -5

x = -5 : (-1)

x = 5
