1)[m]1\frac{5}{12}+x[/m]=0 =>x=0-[m]1\frac{5}{12}[/m] =>x=[m]-1\frac{5}{12}[/m]
2)x-1=0.9 => x=0.9+1 => x=1.9
3) x+17.92=30 => x=30-17.92 => x=12.08
4)100-x=[m]12\frac{7}{30}[/m] => x=100-[m]12\frac{7}{30}[/m] => x=[m]\frac{2633}{30}[/m]=[m]87\frac{23}{30}[/m]
5)x-6.28=0.28 => x=0.28+6.28 => x=6.56
6)x+5= [m]10\frac{3}{20}[/m] => x=[m]10\frac{3}{20}-5[/m] => x=[m]5\frac{3}{20}[/m]
7)0.725-x=0.723 => x=0.725-0.723 => x=0.002
8)x-31.9=2 => x=2+31.9 => x=33.9
9)23.2+x=0.2 => x=0.2-23.2 => x=-23
10)50.32-x=-50.32 => x=-50.32-50.32 => x=-100.64
11)3+x=[m]3\frac{4}{21}[/m] => x=[m]3\frac{4}{21}-3[/m] => x=[m]\frac{4}{21}[/m]
12)-3+x=0.75 => x=0.75+3 => x=3.75
