Solve for x: 4x - 8 = 0.

Solving a linear equation means undoing the operations on the variable. In 4x - 8 = 0, first undo the subtraction by adding 8 to both sides, giving 4x = 8. Then undo the multiplication by dividing both sides by 4, yielding x = 2. A quick check: 4(2) - 8 = 8 - 8 = 0, which fits the equation. Since the coefficient of x is not zero, this gives a single solution: x equals 2.
