Question

Wyznacz a ze wzorów:

k=2a+1
s= a+b/2
M=4-3ba
V=2a/5p+4
R(n-3a)=P

Answer 1

K = 2a + 1
2a = k - 1
a = (k - 1)/2

s = a + b/2
2s = 2a + b
2a = 2s - b
a = (2s - b)/2

M = 4 - 3ba
3ba = 4 - M
a = (4 - M)/3b

V = 2a/(5p + 4)
V(5p + 4) = 2a
a = V(5p + 4)/2

R(n - 3a) = P
Rn - R3a = P
- R3a = P - Rn
3a = -(P - Rn)/R
a = -(P - Rn)/3R = (Rn + P)/3R
