Question

Wyznacz x z poniższych wzorów:

a) t = x/a - 5x

b) p = a + x + ax

c) m = (x+1)p - 3x

d) w = 1/x + p

x/a i 1/x to są ułamki. :)

Answer 1

a) t = x/a  - 5x======================*a

ta = x -5xa

ta = x(1-5a)

x = ta/(1-5a

 

 

b) p = a + x + ax

p-a = x+ax

p-a = x(1+a)

x = (p-a)/(1+a)

 

c) m = (x+1)p  - 3x

m=px+p-3x

m-p = x(p-3)

x=(m-p)/(p-3)

 

d) w = 1/x  + p

wx=1+px

wx-px = 1

x(w-p) = 1

x = 1/(w-p)
