9-) x gun sonra esit olacagini varsayalım;
Mert = Firat
45- x.1= 12+2x
2x+x= 45-12
3x= 33, x= 11 gün.
11-) evli cift sayisi x olsun.
hem erkek hem kadin sayisi x kadar artacagindan;
20+x= 3(4+x)
20+x= 12+3x
3x-x= 20-12
2x= 8, x= 4 olur.
12-) Basamak sayisi x olsun,
cikarken attigi adim sayisi x/2 ,
inerken indiği adim sayisi x/4 olur.
cikarken attığı adim inerken attigi adimdan 40 fazla ise;
x/2= x/4 +40
x/2-x/4= 40
(2x-x)/4= 40
x= 4.40= 160 basamak.
