1) [latex]- \frac{5}{22} -(- \frac{17}{33} )= \frac{-15+34}{66} = \frac{19}{66} [/latex]
2) [latex] \frac{3}{14} - \frac{5}{7} = \frac{3-10}{14}= \frac{-7}{14} =- \frac{1}{2} [/latex]
3) [latex]2 \frac{1}{3}-(-3 \frac{1}{5})= \frac{7}{3}+ \frac{16}{5} = \frac{35+48}{15}= \frac{83}{15}= 5 \frac{8}{15} [/latex]
4) [latex]-8,3-6 \frac{1}{3}=-8 \frac{3}{10} -6 \frac{1}{3}= \frac{83}{10}- \frac{19}{3}= \frac{-249-190}{30} =- \frac{439}{30} =-14 \frac{19}{30} [/latex]
5) [latex]-8,3-(-2 \frac{4}{15})= -\frac{83}{10}+ \frac{34}{15}= \frac{-249+68}{30}=- \frac{181}{30}=-6 \frac{1}{30} [/latex]
6) [latex]-5.4-x=-3.5[/latex]
[latex]-x=-3.5+5.4[/latex]
[latex]x=-1.9[/latex]
7) [latex]x-4.7=-2.34[/latex]
[latex]x=-2.34+4.7[/latex]
[latex]x=2.36[/latex]
8) [latex]x+ \frac{7}{16} = \frac{3}{8} [/latex]
[latex]x= \frac{3}{8} - \frac{7}{16} [/latex]
[latex]x= \frac{6-7}{16} [/latex]
[latex]x= -\frac{1}{16} [/latex]
