Collect variable terms on one side and constant terms on the other side. We will collect variable terms on the left and constant terms on the right. -2x – 4 > x + 5 This is the given inequality. -2x – 4 - x > x + 5 - x Subtract x from both sides. -3x – 4 > 5 Simplify. -3x – 4 + 4 > 5 + 4 Add 4 to both sides. -3x > 9 Simplify.
