1) x – 3 > –9 Add 3 to both sides. 2) –2x + 1 ≤ –11 Subtract 1 from both sides. Divide by 2 and flip the sign to ≥. 3) 10 < –3x + 1 Subtract 1 from both sides. Divide by 3 and flip the sign to > **Whenever you divide by a negative, you flip the sign. To graph: Less/Greater Than (> or <)... Open Circle Less/Greater Than AND equal to (>= or <=)... Closed Circle Greater than... Shading to the Right Less than... Shading to the left.

Solve just as you would an equation. Go ahead.

Pretend there's an equal sign. 2(x + 5) = 8x  8 Solve for x. What would you get for x @mikala1 ?

No. Try again. Show me your steps so that I can see where you're going wrong.

Ihave come out with this 1. First you multiply the number outside the parentheses by both variables inside the parentheses. 2 multiplied by x=2x and 2 multiplied by 5=10 Now you have 2x + 10 > 8x  8 2. Next you have to combine like terms and get them on separate sides. (It's easier to work with positive numbers.) You want the X's on one side and the plain numbers on the other. 2x + 10 > 8x  8 (8 is negative so you want to add it to the 10 on the other side. But remember: what you do to one side you do to the other.) 2x + 10 > 8x 8 + 8 + 8 (When you add 8 to the negative 8, it makes it 0 so you just get rid of it.) Now you have: 2x + 18 > 8x So now you subtract 2x from both sides: 2x + 18 > 8x 2x 2x You now have: 18 > 6x which means you have combined all the like terms. 3. Now you divide the 6x by 6 to get x by itself: 18 > 6x divided by 6= x You now have: 18 > x (Remember: what you do to on side you do to the other so you have to divide 18 by 6.) 18 divided by 6= 3 4. So when it's all finished it looks like this: 3 > x which basically means 3 is more than x.
