    partially yes, but -2x ≤ -12 is not an answer you need to have just x how to remove that -2 from x? just divide by -2 both sides also don't forget when dividing multiplying by negative number this < becomes > and viceversa

    u forgot that u need to change direction of sign when multiplying or dividing as i said so it should be \(x\geq6\) and \(-3>x\)

    also its nicer to write x<-3 than -3>x but both of them are correct answers
