When you add the same number to both sides of an inequality, is the inequality still true? Explain how you know that your conjecture holds for subtracting the same number.

If you add the same number to both sides of an inequality, the inequality is still true.

If you subtract the same number from both sides of an inequality, the inequality is still true.
Subtract 2 from both sides:
x + 2 > 10. X > 8.
All real numbers greater than 8 should satisfy the inequality.
Let x = 9. 9 + 2 > 10.

If you multiply or divide the inequality by the same POSITIVE number, the inequality is still true.
