Answer 1

Question:

Adding 15 to three times a certain number yields 105 .find the number .

$\sf\underline\red{Answer}$

Let us take the number as $\rm{x}$

The number is $\rm{3x}$

According to Question,

$\rm\mapsto{3x+15=105}$

$\rm\mapsto{3x=105-15}$

$\rm\mapsto{3x=90}$

$\rm\mapsto{x=}\dfrac{90}{3}$

$\rm\mapsto{x=30}$

\sf\underline\red{Answer}

Answer

Let us take the number as \rm{x}x

The number is \rm{3x}3x

According to Question,

\rm\mapsto{3x+15=105}↦3x+15=105

\rm\mapsto{3x=105-15}↦3x=105−15

\rm\mapsto{3x=90}↦3x=90

\rm\mapsto{x=}\dfrac{90}{3}↦x=

3

90

\rm\mapsto{x=30}↦x=30
