Question

When 5 is added to a certain number and the result is multiplied by 3 the final answer is 27 what is the original number

Answer 1

The original number is 4

Explanation:

Let x be the number.

5 is added to x => 5+x

When it is multiplied by 3,

3*(5+x) = 27

=> 15 + 3x = 27

Subtract 15,

3x = 27 - 15 = 12

Divide by 3,

x = 4
