wyznacz x z poniższych wzorów t-na gorze x na dole a - 5x m=(x+1)p-3x p=a+x+ax
a-5xm=(x+1)p-3x
a-5mx=xp+p-3x
-5mx-xp+3x=p-a
x(-5m-p+3)=p-a /:(-5m-p+3)
x=(p-a)/(-5m-p+3)
p=a+x+ax
-x-ax=a-p
x(-1-a)=a-p /:(-1-a
x=(a-p)/(-1-a)
a)
a-5x m = (x+1)p-3x
a-5xm = px+p-3x
-5mx- px+3x = p-a
x(3-5m-p) = p-a /:(3-5m-p)
x = (p-a)/(3-5m-p)
b)
p = a+x+ax
a+x+ax = p
x+ax = p-a
x(1+a) = p-a /:(1+a)
x = (p-a)/(1+a)
