The original number.
3x = x + 3 2x = 3 x = 3/2 or 1.5

The original number.
One.
So 25% of the new value is the newly-added 8. Therefore the original value is three times that, i.e. 24. This means that three 8s plus the other 8 - i.e. four 8s - equals 32.
3x1+2=5
3x = x + 3 2x = 3 x = 3/2 or 1.5

Multiplication is repeated addition. 3 x 3 = 3 added three times.
Multiplication is repeated addition. 3 x 3 = 3 added three times.
3. The square root of a number is the number that when multiplied by itself, will give you the original number. Therefore, if you multiply the square root of three by itself, you will get three. A more clear example using whole numbers: the square root of nine times the square root of nine is three times three, which gives you nine, your original number.

3 1/3
It is number 9. If you add 3 three times it becomes 9 and if you multiply 3 by 3; it is 9.
