Linear Inequality Solve One Step

Giovonni solved the inequality. Analyze his work to determine if he made a mistake. If no mistake was made then choose "no mistake". If a mistake was made, then decide which choice describes his mistake.

• No mistake

• He should have added 4x to both sides for his first step.

• He should have subtracted one from nine in his 2nd step.

• He should have flipped the inequality sign when dividing because the coefficient was negative.
