Question

A number is 3 less than three times another number and their sum is 19 then find the number​

Answer 1

Answer:

The Numbers are 5.5 and 13.5

Step-by-step explanation:

Given

Number is = 3 less than three times another

Their sum is = 19

According to the Question -

➡ x + (3x - 3) = 19

➡ x + 3x - 3 = 19

➡ 4x = 19 + 3

➡ 4x = 22

➡ x = 22/4

➡ x = 5.5

One Number = 5.5

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

Second Number =

➡ (3x - 3)

➡ 3(5.5) - 3

➡ 16.5 - 3

➡ 13.5

Second Number = 13.5

The Numbers are 5.5 and 13.5

Verification :-

Add the Numbers

➡ 5.5 + 13.5 = 19

➡ 19 = 19

➡ LHS = RHS

The Numbers are 5.5 and 13.5

Answer 2

Step-by-step explanation:

Given :-

• Number is 3 less then 3 times of other number
• Sum of both numbers is 19

To Fine :-

• Both numbers

Solution :-

Let the number be :-

• One as x
• Second as (3x - 3)

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

According to the question,

Sum of both numbers is 19

$→x + (3x - 3) = 19$

$→x + 3x - 3 = 19$

$→4x - 3 = 19$

$→4x = 19 + 3$

$→4x = 22$

$→x = \frac{22}{4} = \frac{11}{2}$

$→ \fbox{x = 5.5}$

❍ 1st Number is 5.5

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

➩ 2nd Number =

$→3x - 3$

$→3(5.5) - 3$

$→16.5 - 3$

$→13.5$

❍ 2nd Number is 13.5

∴ The numbers are 5.5 and 13.5

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Verification :-

For verification add both the numbers,

$→5.5 + 13.5 = 19$

$→19 = 19$

Hence L.H.S = R.H.S

Therfore the numbers are correct.
