Question

Resolva as equações
a) (2x+1)=24
b) (x/2 + 2) = 0!
c) (x-3)! = 1
d) (n-4)=120
e) (x+3)!/(x+2)!=2
f) (n+1)!/(n-1)!=12
g) (n+1)!/(n-1)!=6

Answer 1

$a) (2x+1)=24\\\\ 2x=24-1\\\\ x=\frac{23}{2}\\\\\\ b) (\frac{x}{2} + 2) = 0!\\\\\ \frac{x}{2} + 2 = 1\\\\ \frac{x}{2} = 1-2\\\\ x = \frac{-1}{2}$

Por ai vai.
