Which of the following are basic rules used for solving algebraic equations?

• Whatever you do to one side of the equal sign, you must copy and do on the other side of the equal sign.

• Negative signs can be ignored.

• Always do the opposite operation.

• Always start on the left side, regardless of where the variable is.

Find the solution.

• X ≤ 10

• X > 2

• X ≥ 10
