Step-by-Step Guide to Solve 12u + 10 = 186

Key Insights

Solving linear equations follows a logical sequence. Here’s how to isolate u in 12u + 10 = 186:

  1. Subtract 10 from both sides
    This eliminates the constant term on the left:
    12u + 10 - 10 = 186 - 10
    12u = 176

  2. Divide both sides by 12
    This isolates the variable u:
    u = 176 ÷ 12
    u = 14.666... or as a simplified fraction: u = 44/3


Verifying the Solution

Final Thoughts

To ensure accuracy, substitute u = 44/3 back into the original equation:

12*(44/3) + 10 = 186
(528/3) + 10 = 186
176 + 10 = 186
186 = 186 ✅

The equation checks out, confirming our solution is correct.


Real-World Applications of Solving Linear Equations

Equations like 12u + 10 = 186 aren’t just textbook exercises. They apply to everyday scenarios:

  • Budgeting: Calculating total costs including fixed expenses and variable units.
