Let x denote the larger number.

Let y denote the smaller number.

The expressions can be written as,

---------(1)

      ----------(2)

We need to determine the numbers.

Value of the numbers:

Solving the two equations using the substitution method.

Substitute in equation (1), we have;

Thus, the value of y is 10.

Substitute in equation (2), we have;

Thus, the value of x is 30.

Thus, the two numbers are 30 and 10.
