Question

The sum of three times a number and 11 is 32 . Find the number.​

Answer 1

Answer:

Let the number = x

Given that,

Sum of three times x and 11= 32

So, 3x + 11 = 32

3x = 32 - 11

3x = 21

x=21/3

x = 7

Answer 2

$\sf\bold{Solution}$

If the unknown number is taken to be $x$,then three times the number is 3$x$ and the sum of 3$x$ and 11 is 32 .

That is , 3$x$ + 11 = 32

•To solve the equation,we transpose 11 to RHS, so that,

3$x$ = 32-11 or 3$x$ = 21

• Now divide both sides by 3

So,

$x \times \dfrac{21}{3}$=7 .

The required number is 7 . (You can check it by taking 3 times 7 and adding 11 to it . It gives 32 as required) .
