wyznacz x ze wzoru:
1) z=a+3x
2) R=x/x-b
3) P=axb
4) S=a/bx
5) T=1/abx
6) y=x-1/2
7) y=2/x-1
8) y=2(x-1)

1) z=a+3x
z-a=3x /:3
z-a/3=x <=> x=z-a/3
2) R=x/x-b /*(x-b)
R(x-b)=x
Rx - Rb=x
Rx-x=Rb
x(R-1)=Rb
x=Rb/R-1
3) P=axb /:ab
P/ab =x <=> x=P/ab
4)S=a/bx /*bx
Sbx=a /:Sb
x=a/Sb
5)T=1/abx /*abx
Tabx=1 /:Tab
x=1/Tab
6) y=x-1/2 /*2
2y=x-1
2y+1=x <=> x=2y+1
7) y=2/x-1 /:(x-1)
y(x-1)=2
yx-y=2
yx=2+y
x= 2+y/y
8) y=2(x-1)
y=2x-2
y+2=2x
y+2/2=x <=> x=y+2/2
9) a=xk+xy
a=x(k+y) /:(k+y)
a/k+y=x <=> x=a/k+y
10) g=2-1/x
g=1/x /*x
gx=1
x=1/g
