Answer 1

1) x+3/4 = 5/16   x= 5/16 - 3/4 = 5/16 - 12/16 = - 7/16
2) x+1 intreg 2/3 =5/6    x= 5/6 - 5/3 = 5/6 - 10/6 = - 5/6 
3) 4+x=3 intreg 1/4     x= 4 - 13/4 = 4/4 - 13/4= - 9 /4 = - 2 intregi 1/4 
4) x+(-5/8) = 7/12      x= 7/12 + 5/8 = 14/24 + 15/24 = 29/24 = 1 intreg 5/29
5) x+3/8 = 27     x= 27 - 3/8 = 26  intregi 5/8 
6) 2,4 + x = 2,8    x = 2,8 - 2,4 = 0,4
7) x+(-7,84) = -5,5    x= -5,5 +7,84 = 2,34
8) x+2intregi 3/8 = 1 intreg 5/6   x= 11/6 - 19/8 = 44/24 - 57/24 = - 13/24
9) -1,2 +x = -5,12      x= -1,2 +(-5,12)   = -6,32  
10 )  x - 4/5 = 8/15     x= 8/15 -4/5 = 8/15 - 12/15 = - 4/15
