Recall
Maths4U Original · Short practice
Solve \(4 x - 4 = x + 17\). A changed constant is used only in the part that explicitly states it.
Solve the equation for x.
Enter one exact number or fraction unless the question specifies rounding. If it asks for a coefficient of π, enter that coefficient only. Give full reasoning separately for written problems.
