    subtract the 7 from the 13, that gives you -2x=6 then divide -2 by six, that then gives you x>-3 you have the flip the switch because you are dividing by a negative

    okay so first you have to subtract 5 from -15 that gives you 6x>7x-20 then you have to subtract 7x from 6x, that gives you -x>-20then to get it non negative multiply the whole problem by -1 so then the answer is x>20
