А) 14-y=19-11y
b) 2x+9=13x
c) 0,5a+11=4-3a
d)1,2n+1=1-n
e)2,6-0,2b=4,1-0,5b
f)(y+4)-(y-1)=6y

$a) ~14-y=19-11y ~~-y+11y=19-14 ~~~10y=5 ~~~y=0,5$

$b)~~ 2x+9=13x ~~~~~2x-13x=-9 ~~-11x=-9 ~~~~x= frac{9}{11}$

$c) ~0,5a+11=4-3a ~~~~0,5a+3a=4-11 ~~~~3,5a=-7 ~~~~a=-2$

$d)~1,2n+1=1-n ~~~~1,2n+n=1-1 ~~~~2,2n=0 ~~~~n=0$

$e)~2,6-0,2b=4,1-0,5b ~-0,2b+0,5b=4,1-2,6 ~~~~0,3b=1,5 ~~~~b=5$

$textup{f)}~(y+4)-(y-1)=6y ~~~~y+4-y+1=6y ~~~~5=6y ~~~~6y=5 ~~~~y= frac{5}{6}$
