Question

1/10у-1/9=10 Выразите у через х

Answer 1

1/10y-1/9x=10

1/10y=10+1/9x

y=10+1/9x / 1/10

y=(10+1/9x)*10

y=100+1 1/9x

Answer 2

$\frac{1}{10}y-\frac{1}{9}x=10\\\\\frac{1}{10}y=\frac{1}{9}x+10\\\\y=\frac{\frac{1}{9}x+10 }{\frac{1}{10} } =(\frac{1}{9} x+10)*10=1\frac{1}{9}x+100\\\\y=1\frac{1}{9}x+100$
