zad1 ;D
Z każdego z podanych nieżej wzorów wyznacz x.
a. P=abx
b. R= ax/b
c. S= a/bx
zad2 ;)
Wyznacz wskazane wielkości:
a. k=7n; n
b. a =k+6; k
c. z=7-y; y
d. d= a+bc; c
e. x= 2k +1; k
f. 2k = 7n+5; n
pilne ;)

Zad. 1
a. P=abx
x= P/ab
b. R= ax/b
ax = R b
x= Rb/a
c. S= a/bx
Sbx = a
x= a/Sb
Zad. 2
a. k=7n; n
n= k/7
b. a =k+6; k
k= a - 6
c. z=7-y; y
y= 7 - z
d. d= a+bc; c
bc= d - a
c= (d-a)/b
e. x= 2k +1; k
2k = x-1
k = (x-1)/2
f. 2k = 7n+5; n
7n = 2k - 5
n = (2k - 5)/7
