7/8-(х+5/12)=5/24 (2/15+у)-3/70=1/10 решить уравнения

7/8-(х+5/12)=5/24

х+5/12=5/24-7/8

х+5/12=5/24- 21/24

х+5/12=-16/24

х-5/12=-2/3

х=-2/3 +5/12

х=-8/12+5/12

х=-3/12=-1/4

(2/15+у)-3/70=1/10  

2/15+у=1/10+3/70

2/15+у=7/70+3/70

2/15+у=10/70

2/15+у=1/7

у=2/15-1/7

у=14/105-15/105

у=-1/105
