Adding both equations eliminates y:
2x = 52 → x = 26
Substitute back:
26 + y = 40 → y = 14
Thus, the larger number is 26 — a result that feels satisfying and intuitive once explained. The method combines algebraic clarity with step-by-step logic — approachable for readers new to equations.

How to Solve The Sum of Two Numbers Is 40, and Their Difference Is 12. What Is the Larger Number?
Here’s a clear, step-by-step breakdown designed to build confidence:
Step 1: Define variables. Let the larger number be x, smaller be y.
Step 2: Write the two equations from the facts:
- Total: x + y = 40
- Difference: x − y = 12
Step 3: Add both equations:
(x + y) + (x − y) = 40 + 12 → 2x = 52
Step 4: Solve for x:
x = 52 ÷ 2 = 26
Step 5: Confirm by finding y: y = 40 − 26 = 14
This process shows how logic clears confusion fast. No hidden steps, no guesswork — just factual alignment.
Common Questions About The Sum of Two Numbers Is 40, and Their Difference Is 12. What Is the Larger Number?
-
How do I set up the equations?
Start by labeling the unknowns and writing both the sum and difference clearly. This structure makes solving intuitive for beginners. -
Can this be solved with estimation?
While estimation helps in approximate thinking, exact numbers are required here — simple algebra delivers precision every time. -
Why not try factoring?
Factoring applies more in advanced equations. For this system, direct substitution or elimination remains fastest and most transparent. -
What if subtraction goes wrong?
Double-check signs: x − y subtracts the smaller from the larger. Mistakenly flipping signs leads to incorrect totals.
