Przekształć podany wzór aby otrzymać:
A) m
E=m*g*h+(m*v2)/2 ;v2 (v do kwadratu)
B) x
kx-my=x
C) x
2x+cx=5
D) x
1/x+1/y=1
Proszę o wszystkie obliczenia!

E=m*g*h+(m*v2)/2 /*2
2E = 2m.g.h + (m.v do 2) / - (m.v do 2)
2E = m (2gh + v do 2) / : (2gh + v do 2)
m = 2E/ (2gh + v do 2)
kx-my=x / -x
kx-my-x = 0 / +my
x (k-1) = my / :(k-1)
x = my/k-1
2x+cx=5
x (2+c) = 5 /: 2+c
x = 5 / 2+c
1/x + 1/y = 1 /. xy
y + x = xy / - x
y = xy-x
y = x (y-1) / :(y-1)
x = y/(y-1)
