Solve the Inequality –2x < 14 for x

-2x<14
Divide each side by -2.
x>-7
Proof: -2(-6)<14 = 12<14
-2(-5)<14 = 10<14
-6 and -5 are both possible substitutes for x that make the inequality true. (Remember: -6>-7;-5>-7; don't get tricked by negatives and positives!)

considering the fact which you have already got the selection with the variable it is x, you divide the two factors with the aid of -2.and additionally opposite the inequality sign it is < to > to clean up for x.You opposite the sign considering the fact which you're dividing the climate with a damaging selection. -2x<14 -2x/-2>14/-2 x>7/-a million or x>-7 you could write the respond in a answer set whilst asked as answer Set={x:x>-7} which ability x searched that x is larger than -7
