Explanation Step 1: Let's denote the two numbers as x and y. We have two equations: 1. x + y = 28 2. x - y = 4 Step 2: Solve the system of equations. Adding the two equations eliminates y: (x + y) + (x - y) = 28 + 4 2x = 32 Step 3: Solve for x. x = 32 / 2 x = 16 Step 4: Solve for y. Substitute x into one of the original equations: 16 + y = 28 y = 28 - 16 y = 12 Step 5: Identify the correct pair of numbers. The numbers are 16 and 12.
