What is the meaning of divide both sides by a number

Answer 1

To "divide both sides by a number" means to divide both sides of an equation or inequality by the same number.

When solving an equation or inequality, the goal is often to isolate the variable on one side of the equation. Dividing both sides by a number helps accomplish this goal as it helps eliminate or cancel out other terms or numbers. By dividing both sides by the same number, you maintain the equality or inequality of the original statement.
