Question

Si al triple de un número le restas 16, obtienes 29. ¿Cuál es ese número?

Answer 1

El número = x
El triple = 3x

Resolvemos : 

3 (x) - 16 = 29

3x = -16 = 29

3x = 29 + 16

3x = 45

x = 45/3

x = 15

Respuesta : El número es = 15

Answer 2

$Hola~~\mathbb{LI} \\ \\ Sea~el~n\acute{u}mero~~---\ \textgreater \ \boxed{x} \\ \\Indica~que: \\ \\ \underbrace{Si~al~triple}_{3}~\underbrace{de}_{X}~\underbrace{un~\acute{u}mero~le~restas~16}_{x-16}, \underbrace{obtienes~29}_{29} \\ \\ La~ecuaci\acute{o}n~seria: \\ \\ 3(x-16)=29 \\ \\ 3x-48=29$

$3x=77 \\ \\ \boxed{x= \frac{77}{3} } \\ \\ comprovamos: \\ \\ 3(x-16)=29~~--\ \textgreater \ tenemos~[x= \frac{77}{3}] \\ \\ 3( \frac{77}{3} -16)=29 \\ \\ \not 3( \frac{77-48}{\not 3})=29$

$29=29~~---\ \textgreater \ queda~demostrado \\ \\ \mathbb{qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqq} \\ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Espero~ter~sirva~saludos!!$
