Practice Equivalence Transformation in Math

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

Operations applied to both sides of an equation that transform its form while leaving its solution set completely unchanged.

Whatever you do to one side, do to the other โ€” the balance stays true.

Example 1

easy
Starting from x + 5 = 12, apply an equivalence transformation to solve.

Example 2

medium
Why is squaring both sides of an equation NOT always an equivalence transformation?

Example 3

easy
What equivalence transformation converts 3x = 15 to x = 5?

Example 4

medium
Why must we NOT multiply both sides of an equation by 0?
