Question

In 63 de lazi sau pus 1365 kg de mere si struguri merele cite 23 kg in fiecare lada iar strugurii cite 20 in fiecare lada. Cite lazi de fiecare fel erau?

Answer 1

$m+s=63- lazi$

$23m+20s=1365 kg$

$23m+20s=1365$

[tex]23(63-s)=1365 1449-23s+20s=1365 1449-1365=23s-2-s [/tex]

$s=84/3$

$s=28$

[tex]m+s=63 [/tex]

$m=63-s$

$m=63-28$

$m=35$
