1)51+3у=57+у 2)-50(-3х+10)=-20 3)-62(2у+22)=-1860 4)-11х+52=41х 5)14(3у-5)=19у-1 6)11(8+9х)=88+х

Answer 1

51+3у=57+у

-y+3y=-51+57

2y=6

y=3

-50(-3х+10)=-20

150x-500=-20

150x=480

x=3,2

-62(2у+22)=-1860

-124y-1364=-1860

-124y=-496

y=4

-11х+52=41х

-11x-41x=-52

-52x=-52

x=1

14(3у-5)=19у-1

42y-70=19y-1

42y-19y=70-1

23y=69

y=3

11(8+9х)=88+х

88+99x=88+x

-x+99x=-88+88

98x=0

x=0

Answer 2

51+3у=57+у

-y+3y=-51+57

2y=6

y=3

-50(-3х+10)=-20

150x-500=-20

150x=480

x=3,2

-62(2у+22)=-1860

-124y-1364=-1860

-124y=-496

y=4

-11х+52=41х

-11x-41x=-52

-52x=-52

x=1

14(3у-5)=19у-1

42y-70=19y-1

42y-19y=70-1

23y=69

y=3

11(8+9х)=88+х

88+99x=88+x

-x+99x=-88+88

98x=0

x=0
И ВСЕ)))
