5x-9%3E2x-7 Start with the given inequality



5x%3E2x-7%2B9Add 9 to both sides


5x-2x%3E-7%2B9 Subtract 2x from both sides


3x%3E-7%2B9 Combine like terms on the left side


3x%3E2 Combine like terms on the right side


x%3E%282%29%2F%283%29 Divide both sides by 3 to isolate x



x%3E2%2F3 Reduce

--------------------------------------------------------------
Answer:
So our answer is x%3E2%2F3 (which is approximately x%3E0.667 in decimal form)




So the answer in interval notation is


Here's the graph of the solution set










5%283m-%28m%2B4%29%29%3C-2%28m-4%29+ Start with the given inequality


15m-5%28m%2B4%29%3C-2%28m-4%29+ Distribute




15m-5m-20%3C-2m%2B8 Distribute


10m-20%3C-2m%2B8 Combine like terms on the left side


10m%3C-2m%2B8%2B20Add 20 to both sides


10m%2B2m%3C8%2B20 Add 2m to both sides


12m%3C8%2B20 Combine like terms on the left side


12m%3C28 Combine like terms on the right side


m%3C%2828%29%2F%2812%29 Divide both sides by 12 to isolate m



m%3C7%2F3 Reduce

--------------------------------------------------------------
Answer:
So our answer is m%3C7%2F3 (which is approximately m%3C2.333 in decimal form)



So the answer in interval notation is
