the ratio of two numbers is 5/4 and the first number is 7 more than the second number. to determine each of these numbers, let x be the first number. Since the first number is 7 more than the second number, and since the first number is x, what is the second number?

Let first number be X.

Second number = X - 7 (first is 7 bigger than second)
Ratio of two numbers = Bigger number / Smaller Number

BIgger number is the first number.

Ratio of two numbers = (x) / (x-7) = 5/4
By simplifying:
4x = 5(x-7)
x=?

Thus,
x-7 = ?
