    on the right hand side... \[\frac{ 1 }{ 3 } (9a -18)\] so to simplify this, we would do... \[\frac{ 1 }{ 3 } . 9a - \frac{ 1 }{ 3 } . 18\] thats how we open a bracket, so we multiply the term outside to both the inside terms, so can you please simplify this?

    not quite, if you multiply the above equation out, you should get 3a - 6 for the night hand side, do you see why? all I've done here is expand \[\frac{ 1 }{ 3 }9a - \frac{ 1 }{ 3 }18\]

    so the answer is A right because a= 2

    remember we have to let the left hand side equal to our simplifies right hand side and then solve

    so now we go back to our original equation where we had \[6 - a = \frac{ 1 }{ 3 } (9a -18)\] except, we've already simplified the rightt hand side above so its just... \[6 - a = 3a -6\]

    um, not exactly, you would take the -a from the left hand side over to the right so you get 6 = 3a + a -6

  27. FireKat97

    and do the same thing with the 6 on the right hand side, you want to take that over to the left
