Suppose "n" is a number.
Five times the difference of a number and three: 5(n - 3)
...is four less than four times the number: 4n - 4
The equation: 5(n - 3) = 4n - 4
Solve,
5(n - 3) = 4n - 4
5n - 15 = 4n - 4 ---> 5n - 4n = 15 - 4
n = 11
Verify:
5(n - 3) = 4n - 4 --> 5(11 - 3) = 4(11) - 4 --> 40 = 40
Thus, n = 11 is the number.
