Potrzebuje pomocy z matematyki. Zadania w załączniku, tylko te dwa.
zad 1
a(4-y) - x = b
a(4-y) = b + x / : a
4-y = b + x / a -> / to ułamek
- y = b + x / a - 4
y = - ( b + x / a - 4)
y = 4 - b + x / a
odp. B
zad 2
kb - b = x
b(k - 1) = x / : (k - 1)
b = x/(k - 1)
odp. A
" Life is not a problem to be solved but a reality to be experienced! "
