Answer 2

Step-by-step explanation:

Let the number be x So

$\large{\blue{\bigstar}} \: \: {\underline{\boxed{\red{\sf{4x= x+45 }}}}}</strong></p><p></p><p></p><p>[tex]\large{\blue{\bigstar}} \: \: {\underline{\boxed{\red{\sf{ }4x-x=45}}}}$

$\large{\blue{\bigstar}} \: \: 3x = 15$

$\large{\blue{\bigstar}} \: \: {\underline{\boxed{\red{\sf{ X=\qquad\longrightarrow\quad\sf \dfrac{\cancel{3}}{\cancel{15}}}}}}}$

So,

$\large{\blue{\bigstar}} \: \: {\underline{\boxed{\red{\sf{ }}X= 5}}}$
