Sum

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

Solution

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

That is, 3x + 11 = 32.

3x = 32 – 11
3x = 21

Now, divide both sides by 3

So, x = 21/3 = 7

The required number is 7.
