Question

Решите плиз! (^_^)
(4 1/9-а) +8 5/9=9 2/9
500-400:(х+43)=495

Answer 1

1)
$(4 frac{1}{9} -a) +8 frac{5}{9} =9 frac{2}{9}$
$4 frac{1}{9} -a=9 frac{2}{9} -8 frac{5}{9}$
$4 frac{1}{9} -a= frac{6}{9}$
$a=4 frac{1}{9} -frac{6}{9}$
$a=3frac{4}{9}$

Ответ: $3frac{4}{9}$

2)
$500-400:(x+43)=495$
$400:(x+43)=500-495$
$400:(x+43)=5$
$x+43=400:5$
$x+43=80$
$x=80-43$
$x=37$

Ответ: $37$
