Best ResponseYou've already chosen the best response.0Ok. So lets get started! First we must get x alone and the numbers alone. (Think of this. X hates friends/numbers. Numbers love other numbers.) So we must get rid of all the numbers that are near X so we get rid of 4. (GOLDEN RULE: WHAT YOU DO TO ONE SIDE YOU MUST DO TO THE OTHER.) dw:1442273316056:dw This makes 2x > 10 What do we do next?

Best ResponseYou've already chosen the best response.0−2x − 4 > 8 Isolate x on one side. So we need to move 4 over. Since it's a negative number, we have to add it (Add on BOTH sides). 2x 4 > 8 + 4 +4 4 + 4 = 0 8 + 4 = 12 Now we have: 2x > 12 We need to divide each side by 2 now to isolate x. 2x/2 > 12 Before dividing, see if the number is a negative or positive. 2 is negative so we need to SWITCH the inequality sign because we're dividing by a negative. So, this > becomes <. x < 6. < Answer. (:
