I am thinking of a number. If you subtract 3 from my number and then multiply by 4, the result is 28. What number am I thinking of?

Question

28 divided by 4, then add 3

Answer 1

If n is the number then 4(n-3)=28, n-3=7, so n, the number,=10.

Another way is to reverse all the arithmetic:

The result after multiplication was 28, so the opposite of multiplication is division therefore divide 28 by 4 to get 7.

The number less 3 is 7, so add (opposite of subtract) 3 to get the number making the number 10.
