x + y = 30 ... (Equation 1) x - y = 8 ... (Equation 2) We can solve these equations by adding them together, which eliminates y: 2x = 38 Dividing both sides by 2 gives us: x = 19 Now that we have x, we can find y by substituting x into Equation 1: 19 + y = 30 Subtracting 19 from both sides gives us: y = 11 Now that we have both x and y, we can find their product: Product = x * y = 19 * 11 = 209
If the sum of two numbers is 30 and their difference is 8, what is their product?
