Question: Solve for $ x $ in the equation $ 3(x - 4) + 7 = 2(x + 5) $. - inBeat

Understanding the Context

In today’s fast-paced, information-driven culture, users seek clarity on practical math challenges. Social media, education platforms, and mobile-first tutorials frequently highlight foundational algebra problems like this one, reflecting growing interest in numeracy and logical thinking. Parents, students, and self-learners in the US are turning to clear, confidence-building explanations—avoiding jargon or complexity—to build competence in math basics. The equation’s accessibility makes it perfect for mobile learners seeking structured, digestible learning without overwhelm.

How to Solve $ 3(x - 4) + 7 = 2(x + 5) $: A Step-by-Step Breakdown

To solve for $ x $, begin by expanding both sides carefully.
First, distribute:
$ 3x - 12 + 7 = 2x + 10 $
Simplify each side:
$ 3x - 5 = 2x + 10 $

Next, isolate the variable by subtracting $ 2x $ from both sides:
$ 3x - 2x - 5 = 10 $
Which simplifies to:
$ x - 5 = 10 $

Key Insights

Finally, add 5 to both sides to isolate $ x $:
$ x = 15 $

This clean process shows how balancing both sides systematically leads to the correct solution—making algebraic reasoning accessible and predictable.
