Distribute on both sides:
Left side: $5 \cdot 2x - 5 \cdot 3 = 10x - 15$
Right side: $3 \cdot 3x + 3 \cdot 4 = 9x + 12$
Now the equation reads:
$10x - 15 = 9x + 12$
Subtract $9x$ from both sides to gather $x$ terms on one side:
$10x - 9x - 15 = 12$
Simplify:
$x - 15 = 12$
Add 15 to both sides to isolate $x$:
$x = 12 + 15$
$x = 27$
This structured approach breaks complexity into digestible steps, making the process transparent and easy to follow—key for ample dwell time and deep engagement on mobile devices.

Q: What does it mean when we “solve for $x$”?
It means finding the specific numerical value of $x$ that makes both sides of the equation equal. This practice strengthens reasoning and pattern recognition—skills transferable across disciplines.
Q: Why must I distribute terms first?
Distributing eliminates parentheses, revealing all variable and constant values. Skipping this step risks incorrect comparisons and errors, which explains the popularity of focused explanation articles.
Q: Can $x$ ever have more than one solution here?
Only if coefficients lead to
