    x - 3 < -9 ---- add 3 to both sides x < -9 + 3 x < - 6 x + 5 >= 12 ---- subtract 5 from both sides x >= 12 - 5 x >= 7 Learn this : if there is an equal sign in the problem, it will have an closed circle if there is no equal sign, it is an open circle < less then means shading to the left > greater then means shading to the right do you have any ideas what the answer is now ??

    the -6 does not have an equal sign, so it is an open circle.....and since x < -6, it is shaded to the left. the 7 does have an equal sign, so it is a closed circle...and since it is greater then, it is shaded to the right. any thoughts on the answer now ?
