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
