solve liek a normal equation, except when you divide or muliply by a negative, flipi the sign direction 10. divide both sides by -3 flip sign p-7≤-7 add 7 to both sides p≤0 so put a circle at 0 and shade it in and shade to the left and draw an arrow there (see attachment) 12. times both sides by 15 -9+a>15 add 9 to both sides a>24 put an open circle at 24 and go to the right (see attachment)
