Astore sells markers in packs of 14 pencils in packs of 5. blaine wants to buy an equal number of markers annd pencils. what is the minimum numbre of markers blaaine would have to buy?

The key idea here is that we can't have half a pack (the store owner would be really angry if you cut the packs!).  therefore we are really finding the least common multiple of 14 and 5.  to find lcm is really hard to explain with the limited technology on this website.  i highly recommend you search up ladder method online.  i can, however, tell you that the lcm of 14 and 5 is 70 so 70 is the minimum NUMBER of markers (not packs) that  blaaine would have to buy.

What are the following algebraic equations. you need to post those if you want the answer
