Let's call the unknown number x. We can set up the equation as 4(6 + x) = 56. By distributing the 4, we get 24 + 4x = 56. Subtracting 24 from both sides gives us 4x = 32. Finally, dividing both sides by 4 gives us x = 8. Thus, the unknown number is 8.

The quotient of the sum of a number and three, and four is seven
Call your number some variable, for example, "n". Twice the number would be 2n, adding four to that you get 2n + 4, and six times all that is 6(2n + 4), which is the same as 12n + 24.
