Total: x + 2x = 3 → 3x = 3 → x = <<3/3=1>>1 - Portal da Acústica

Understanding the Context

The Equation: x + 2x = 3

At its core, this equation represents a basic arithmetic relationship. On the left side, we have variable x added to two times itself (2x). Together, these combine into a single term:
x + 2x = 3x

So, the equation simplifies to:
3x = 3

Solving for x

Key Insights

To find the value of x, we isolate the variable by dividing both sides of the equation by 3:
3x ÷ 3 = 3 ÷ 3

This leads to:
x = 1

Why This Format Matters

This straightforward equation demonstrates key algebraic principles, such as combining like terms and solving linear equations — essential skills in mathematics education and real-world applications. Understanding how to solve for x مثل (like “x equals”) reinforces logical thinking and problem-solving abilities.

Final Thoughts

Think of it this way: if x represents a number, then 2x is twice that number. Together, they make 3x. Setting 3x equal to 3 means “three times that number equals three.” Only one number fits — x = 1 — proving how powerful simple equations can be.

Applications in Real Life

Equations of this form appear in everyday situations, from budgeting and measuring ingredients to calculating time or distance. Mastering these basic solves lays a strong foundation for more complex math challenges.

Final Answer

To recap:
Start with:
x + 2x = 3
Combine terms:
3x = 3
Solve for x:
x = 3 ÷ 3 = 1

So, x = <<3/3=1>>1
