Question

Afla numarul x din egaltatiile:
x-( 4 supra 9 + 5 supra 9 - 6 supra noua) =4supra5 +1 supra 5
Va rog sa ma ajutati :)

Answer 1

x-3/9=5/5
x-1/3=1
x=1+1/3amplificam
x=3/3+1/3
x=4/3

Answer 2

$x-( \frac{4}{9}+ \frac{5}{9} - \frac{6}{9})= \frac{4}{5}+ \frac{1}{5}$
$x- \frac{1}{3} =\frac{5}{5}$$=1$
$x= \frac{1}{3} +1= \frac{1}{3} + \frac{1}{1} = \frac{1+3}{3}$
$x= \frac{4}{3} .$
