Practice Isolating Variable in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
Rearranging an equation by applying inverse operations until the variable stands alone on one side.
Peel away everything around x until only x remains: x = answer.
Example 1
easyIsolate y in 2x + y = 10.
Example 2
mediumSolve A = \frac{1}{2}bh for h.
Example 3
mediumSolve for y: 3(2y - 4) + 5 = 2y + 9
Example 4
easyIsolate x in x - 7 = 3.
Example 5
hardSolve P = 2l + 2w for w.
