Practice Balance Principle in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
The rule that any operation applied to one side of an equation must also be applied to the other side to preserve equality.
An equation is like a balanced scale—add weight to both sides equally.
Example 1
easySolve \(x + 7 = 15\) using the balance principle.
Example 2
mediumSolve \(3x - 4 = 14\) using the balance principle, showing all steps.
Example 3
easySolve \(n - 9 = 6\) using the balance principle.
Example 4
mediumSolve \(\frac{x}{4} + 3 = 10\).
