Z każdego wzoru wyznacz b:


2a+b=c



g=23b


et - kb = f




w - f = d(a+b)




d-bk= s +m

Odpowiedź :

Obliczenia :

2a + b = c

b = -2a + c

g = 23b

23b = g

b = g/23

et - kb = f

-kb = f - et

b = (f - et)/(-k)

b = (-f + et)/k

w - f = d(a + b)

a + b = (w - f)/d

b = (w - f)/d - a

d - bk = s + m

-bk = s + m - d | * (-1)

bk = -s - m + d

b = (-s - m + d)/k
