Question

Adding 15 to 13 times a whole number gives 93 there a number is

Answer 1

Question :-

• Adding 15 to 13 times a whole number gives 93. Find the number.

Answer :-

• The whole number is 6.

Given :-

• Adding 15 to 13 times a whole number gives 93.

To find :-

• The number.

Step-by-step explanation :-

Let the whole number be "x".

13 times the whole number = 13x.

15 added to 13 times the whole number = 13x + 15.

The result is 93, which means that 13x + 15 is equal to 93.

------------------------

Hence,

$\longmapsto\sf13x + 15 = 93$

Transposing 15 from LHS to RHS, changing it's sign,

$\longmapsto\sf13x = 93 - 15$

Subtracting 15 from 93,

$\longmapsto\sf13x = 78$

Transposing 13 from LHS to RHS, changing it's sign,

$\longmapsto\sf x = \dfrac{78}{13}$

Dividing 78 by 13,

$\longmapsto\overline{\boxed{\sf x = 6}}$

------------------------

• Hence, the required number is 6.
