The correct Answer is:
To solve the problem step by step, we will define the two numbers and set up equations based on the information given. ### Step 1: Define the Variables Let the larger number be \( x \) and the smaller number be \( y \). According to the problem, we know that: - The larger number exceeds the smaller number. - Therefore, we can write: \[ x > y \] ### Step 2: Set Up the First Equation The problem states that the difference between the two numbers is 26. This can be expressed as: \[ x - y = 26 \] (Equation 1) ### Step 3: Set Up the Second Equation The problem also states that the larger number exceeds thrice the smaller number by 4. This can be expressed as: \[ x - 3y = 4 \] (Equation 2) ### Step 4: Solve the Equations Now we have a system of two equations: 1. \( x - y = 26 \) 2. \( x - 3y = 4 \) We can solve these equations simultaneously. Let's start by solving Equation 1 for \( x \): \[ x = y + 26 \] ### Step 5: Substitute into the Second Equation Now, substitute \( x \) from Equation 1 into Equation 2: \[ (y + 26) - 3y = 4 \] This simplifies to: \[ y + 26 - 3y = 4 \] \[ -2y + 26 = 4 \] ### Step 6: Isolate \( y \) Now, isolate \( y \): \[ -2y = 4 - 26 \] \[ -2y = -22 \] \[ y = \frac{-22}{-2} = 11 \] ### Step 7: Find \( x \) Now that we have \( y \), we can find \( x \) using Equation 1: \[ x = y + 26 \] \[ x = 11 + 26 = 37 \] ### Conclusion The two numbers are: - Larger number \( x = 37 \) - Smaller number \( y = 11 \) ### Final Answer The numbers are \( 37 \) and \( 11 \). ---
