Question

If 5 is subtracted from 3 times a number the result is 16. Find the number also do verification.​

Answer 1

ANSWER

Let the number be x.

As per question, we have

3x−5=16

⇒3x=16+5

⇒3x=21

⇒x=7

Therefore, the number is 7.

Answer 2

Given:

5 = 3x-5 = 16

To find:

Value of "x"

Solution:

Let required number = x

3 times of number = 3x

Subtract 5 = 3x-5

Result = 16

3x-5 = 16

Adding 5 to both sides

3x-5+5 = 16+5

3x-21

Dividing both sides by 3

3x/3 = 27/3

x = 7

Solution set = {7}

Answer:

Value of x = 7

Verification:

3x-5 = 16

3(7)-5 = 16

21-5 = 16

16-16 which is true.
