When the sum of 28 and a certain number is divided by 5 the result is equal to triple the original number. What is the number
Let's say the certain number is x.
The problem states that the sum of 28 and this number is divided by 5, the result is equal to three times the original number, x.
So, (28 + x) / 5 = 3x.
To solve this equation, we can multiply both sides by 5 to get rid of the denominator:
28 + x = 15x.
Now, let's solve for x.
Subtract x from both sides: 28 = 14x.
Divide both sides by 14 to solve for x: x = 2.
Therefore, the number is 2.
