How to Solve Simple Linear Equations: The Case of x + y = 25 and x - y = 5
Mathematics introduces us daily to clever problems that sharpen our logic and problem-solving skills. One classic example involves two unknowns, represented by numbers x and y, and two straightforward equations:
- x + y = 25
- x - y = 5
Understanding the Context
These equations may seem simple, but mastering their solution sets a strong foundation for tackling more complex math challenges. Let’s walk through the step-by-step process of solving these equations using the elimination method — a powerful technique that leverages adding equations to eliminate variables and find answers quickly.
The Equations at a Glance
We start with:
Key Insights
- x + y = 25
- x - y = 5
Our goal is to find the values of x and y using these two simultaneous equations.
Step 1: Sum the Two Equations
The key strategy here is adding the equations. By aligning like terms vertically:

x + y = 25<br/>
+ x - y = 5 </p>
<hr/>
<p>2x = 30<br/>
Notice how y and -y cancel each other out, simplifying the problem to:
2x = 30
Step 2: Solve for x
Divide both sides by 2 to isolate x:
x = 30 ÷ 2 = 15
Now that we know x equals 15, we can substitute this value into one of the original equations to find y.
