let x represent one of the numbers and y the other number. Set up two equations to solve: Equation 1, sum of the numbers: x + y = 53 Equation 2, difference of the numbers: x - y = 25 System of equations: x + y = 53 x - y = 25 ---------------- 2x = 78 x = 39 Solve for y: 39 + y = 53 y = 14 The numbers are 39 and 14.
