Best ResponseYou've already chosen the best response.1or you can combine 218 to get 13 this gives you 8p+13 = 29 then you can subtract 13 from both sides to get 8p = 2913

Best ResponseYou've already chosen the best response.1so 8p = 16 p = ??

Best ResponseYou've already chosen the best response.0Fantastic! Now, solve for x! Tell me what you do next :o)

Best ResponseYou've already chosen the best response.0Nope. Remember, when you take from one side, you must take from the side with the x. So instead, take the 7.5 from the side with the x. :o)

Best ResponseYou've already chosen the best response.0\[\frac{ a5 }{ 10 }=\frac{ 2a3 }{ 5 }\] Cross multiply :o) \[10(2a3)=5(a5)\] Distribute \[20a30=5a25\]\[15a30=25\]\[15a=5\]\[a=\frac{ 5 }{ 15 }\]\[a=\frac{ 1 }{ 3 }\] Do you see how I got that? :o)

Best ResponseYou've already chosen the best response.0Wait which do I cross multiply?

Best ResponseYou've already chosen the best response.0For the original equation, you're first going to cross multiply. So, a5 times the 5, and then the 2a3 times the 10.
