    add 3 on both sides. You'll get -9x >= 54 Divide or multiply both sides by -1.. such as -9x * 1 >= 54*-1 since value of 54 is now negative, so we flip the inequality sign.. therefore 9x<= -54 divide both sides by 9 and solve.. you'll get x <=-6 Hope this helps

    so i know i am supposed to add the two to the seven which is ten and then to the -3x but that stays the same for some reason then i forgot what to do next haha

    newho back to the sum -3x -2 > 7 its same as before.. Take the constant terms onright hand side, by contant terms i mean the numerical terms without variables..

    great now we have reduced the equation to -3x>7 Multiply or Divide both sides by -1 The sign will be flipped as at both the sides we are multiplying by negative 1..

    that is 3x <-7 or x<-7/3

    3x<-9 that is x<-3

    ok so after i take the 2 and add it to 7 to get 9 i also add it to the -3x and then i have -3x>9 then i how do i know if i am to multiply or divide to get the answer x<-3

    well it doesnt't matter.. you divide a no by -1 or multiply a number -1 you get the same answer... get it?

    we still have a co efficient that is the number that you've along with your variable in 3x<-9 ryt??

    what we want is value of just x and not 3x.. So in order to find the value of just x we divide both the sides by 3..
