The sum of the two numbers is 47: (x + y = 47) ---(Equation 1) The subtraction of the two numbers is 13: (x - y = 13) ---(Equation 2) To find the values of (x) and (y), we can solve this system of equations. We can solve this system by adding Equation 1 and Equation 2: ((x + y) + (x - y) = 47 + 13) (2x = 60) (x = 30) Now, substitute the value of (x) into Equation 1 to solve for (y): (30 + y = 47) (y = 47 - 30) (y = 17) Therefore, the two numbers are 30 and 17, as their sum is 47 and their subtraction is 13.
