Z każdego z poniższych wzorów oblicz "z" i sformułuj odpowiednie założenia.
a) az+b=cd
b) a(z+b)+cz=d
c) az+b=cz+d
az = cd - b
z = (cd - b)/a
a różne od 0
az + ab + cz = d
az + cz = d - ab
z ( a + c ) = d - ab
z = ( d - ab ) / ( a + c )
(a + c) różne od 0
c) az + b = cz + d
az - cz = d - b
z (a - c) = d - b
z = (d - b) / (a - c)
(a - c) różne od 0
a) az = cd - b /:a0
b) az + ab +cz = d
z(a + c) = d - ab /:(a + c)0
z = (d - ab)/(a + c)
c) az - cz = d - b
z(a - c) = d - b /:(a - c)0
z = (d - b)/(a - c)
