11x - 15 = 12

Whether you're a student working through schoolwork or an aspirant preparing for standardized tests, mastering this type of equation opens doors to more complex mathematical thinking.


What Is the Equation 11x - 15 = 12?

The expression 11x - 15 = 12 is a linear equation with one variable, x. The goal is to isolate x and determine its value by performing inverse operations on both sides.


Step-by-Step Solution

  1. Start with the original equation:
    11x - 15 = 12

  2. Add 15 to both sides to eliminate the constant on the left:
    11x - 15 + 15 = 12 + 15
    11x = 27

  3. Divide both sides by 11 to isolate x:
    x = 27 ÷ 11
    x = 27/11

✅ Final solution:
x = 27⁄11 (or approximately 2.45)
