Solve for x: 3x + 7 = 25.

Explanation:
Solving a linear equation means undoing the operations on the variable to isolate it. For 3x + 7 = 25, first subtract 7 from both sides to cancel the added seven: 3x = 18. Then divide both sides by 3 to undo the multiplication: x = 6. Verifying by substitution shows 3(6) + 7 = 18 + 7 = 25, which matches the right side. The essential idea is applying inverse operations step by step to get x by itself.
