Question

O dobro de meu antecessor menos 3,e igual a 25 que numero natural sou eu

Answer 1

Let's assume that natural number as x

Double my predecessor minus 3

$=2x-3$

and we have

and equal to 25

so, we get

$2x-3=25$

now, we can solve for x

Add both sides by 3

$2x-3+3=25+3$

$2x=28$

Divide both sides by 2

$x=14$

So, that natural number is 14.........Answer
