Question

X+1 supra x+4 =5supra8 va rog ajutati-ma!!dau coroana

Answer 1

(x+1)/(x+4) = 5/8
8(x+1) = 5(x+4)
8x+8 = 5x+20
8x-5x = 20-8
3x = 12
x = 12:3
x = 4

Answer 2

$\frac{x+1}{x+4} = \frac{5}{8} \\ \\ 8(x+1)=5(x+4) \\ \\ 8x+8=5x+20 \\ \\ 8x-5x=20-8 \\ \\ 3x=12=\ \textgreater \ x-12:3=\ \textgreater \ x=4$
