I got up at  9 o,clock.In the bathroom I washed my hands face and cleaned my teeth .
I had jam and bread and drank milk for breakfast.Then I ran to school 
In the evening I sat in armchair read Tiny s fairy tales and watched TV At 10 oclock I went to bed

1) (14 - 15,8) - (5,8 + 4) =
= 14 - 15,8 - 5,8 - 4
= 14-4 - 15,8 - 5,8 = 10 - 21,6 = -11,6

2) -(18 + 22,2) + (-12 + 22,2) - (5 - 12) =
= -18 - 22,2 - 12 + 22,2 - 5 + 12 =
= -22,2 + 22,2 - 12 + 12 - 18 - 5 = 18 - 5 = -23

0,8(0,5+2х)=2х+0,4
0,4+1,6х=2х+0,4
2х-1,6х=0
0,4х=0
х=0
