Question

calcule o valor de X na igualdade  x+x/3+x/9+x/27=200/27

Answer 1

$x+\frac{x}{3}+\frac{x}{9}+\frac{x}{27}=\frac{200}{27}\\ \\ Multiplicando \ todos \ os \ termos \ por \ 27:\\ \\ 27x+9x+3x+x=200\\ \\ 40x=200\\ \\ x=\frac{200}{40}\\ \\ \boxed{x=5}$

Answer 2

$\frac{27x}{27} + \frac{9x}{27} + \frac{3x}{27} + \frac{x}{27} = \frac{200}{27} \\ 27x+ 9x+3x + x = 200 \\ 40x = 200 \\ x=\frac{200}{40} => x =5$

Tira o MMC DE 3 | 9 | 27 = 27
