Sagot :
boşken 100 ton olsun 3/4 ü boşken 75 ton olur kamyonun yarısı dolu ise 50 ton olurdu o zaman
(100-75).2 dir cevap yani (x-y).2 yada 2y-x dir işte testte yerine koy rakamları nerde 50 çıkarsa
yüke 4a diyelim
x+a=y dir
x+2a=?
1. denklemden a=y-x geldi
2. denklemde yerine yazarsak
x+2(y-x)=?
x+2y-2x
Cevabımız 2y-x olur
