-7x%3C14 Start with the first inequality



x%3E%2814%29%2F%28-7%29 Divide both sides by -7 to isolate x (note: Remember, dividing both sides by a negative number flips the inequality sign)



x%3E-2 Divide

--------------------------------------------------------------
Answer:
So our first answer is x%3E-2









3x%2B2%3C8 Start with the second inequality



3x%3C8-2Subtract 2 from both sides


3x%3C6 Combine like terms on the right side


x%3C%286%29%2F%283%29 Divide both sides by 3 to isolate x



x%3C2 Divide

--------------------------------------------------------------
Answer:
So our second answer is x%3C2



So we have the answers:

x%3E-2 and x%3C2


which combine to the compound inequality


-2%3Cx%3C2
