Odpowiedź:
x = k + 6
k = x - 6
y = a + xc
xc = y - a
c = (y - a)/x
z = 7 - a
a = 7 - z
x = 2n + 1
2n = x - 1
n = (x - 1)/2
t = 1/a - 5ax
at = 1 - 5a²x
5a²x = 1 - at
x = (1 - at)/5a²
a = x + 1/y
ay = yx + 1
ay - yx = 1
y (a - x) = 1
y = 1/(a - x)
jeżeli natomiast równanie ma postać :
a = (x + 1)/y
ay = x + 1
y = (x + 1)/a
