Problem
Solve the equation \(4x~=~28\). What is \(x\)?
Big Picture
What this problem is really about
The coefficient means the unknown has been multiplied by four, not increased by four. Use the inverse operation by dividing both sides by that coefficient; this leaves one copy of the unknown while preserving equality. Multiplying the result by four should reproduce the original total.
