Hint:
either distribute to get
4j  28 = 12
or
divide both sides by 4 to get
j  7 = 3

14p+218=6p+29
14p+218  6p = 29
then what

Add 8? I don't know

or 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

Nope. 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)

\[\frac{ a5 }{ 10 }=\frac{ 2a3 }{ 5 }\]
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)

Wait which do I cross multiply?

Butterfly16
Best Response

For the original equation, you're first going to cross multiply. So, a5 times the 5, and then the 2a3 times the 10.
