Решите уравнения:
1) 1/5x = -13
2) 15 - (3x - 1) = 40
3) 8x - (2x + 4) = 2 * ( 3x - 2)
4) (6 - 1,2x) * (-x - 4x + 10x - 15) = 0
5) 3 * (2x - 1) - 5 * (7 - x) = 8 * (1 - x) - 3 * (x + 5)
6) 3-2x/4 = -3x-1/7

2) 15-(3x-1)=40

15-3x+1=40

-3x=40-15-1

-3x=24

x=24/(-3)

x=-8

3) 8x - (2x + 4) = 2 * ( 3x - 2)

8x-2x-4=6x-2

8x-2x-6x=2+4

-4x=6

x=6/(-4)

x=-1.5

4) (6 - 1,2x) * (-x - 4x + 10x - 15) = 0

6-1.2x*-x-4x+10x-15=0

-1.2x*-5x+10x=0-6+15

-6x=9

x=9/(-6)

x=-1.5
