1-2x%3E=7 Start with the first inequality.


-2x%3E=7-1 Subtract 1 from both sides.


-2x%3E=6 Combine like terms on the right side.


x%3C=%286%29%2F%28-2%29 Divide both sides by -2 to isolate x. note: Remember, the inequality sign flips when we divide both sides by a negative number.


x%3C=-3 Reduce.

So the first part of our answer is x%3C=-3






4x-3%3E=21 Move onto the second inequality.


4x%3E=21%2B3 Add 3 to both sides.


4x%3E=24 Combine like terms on the right side.


x%3E=%2824%29%2F%284%29 Divide both sides by 4 to isolate x.


x%3E=6 Reduce.


So the second part of our answer is x%3E=6





------------------------ Summary ------------------------


So together our answers are

x%3C=-3 and x%3E=6


However, there is no such number that is less than or equal to -3 AND greater than or equal to 6. So there is no resulting solution set. So it is not possible to graph the solution set.
