\[{z\over-28}= 49-44\]\[{z\over-28}=5\]\[z=-140\]
anonymous
  • anonymous
How did you get -140? I got up to z/-28=5, but I don't know how you did the rest.
anonymous
  • anonymous
You bring -28 over the other side, thereby multiplying 5 by -28.

\[z/-28+44 = 49\] first you might like to multiply by reciprocal -28+44 ( z /-28+44 ) = 49 (-28+49) z = 49 (- 28 + 49) can you do the rest?

\[{z}= 5\times-28 \]
anonymous
  • anonymous
Ok.
anonymous
  • anonymous
just multiply the whole equation by -28+44 first this will make your problem much easier
anonymous
  • anonymous
its just the same as what order did
anonymous
  • anonymous
but faster :P
anonymous
  • anonymous
I've never seem your method.... I find my method pretty neat ;)
anonymous
  • anonymous
well it just the same i just do it in 1 step z/-28+44 = 49 -28+44 [ z / -28+44 = 49 ] fraction go bb
anonymous
  • anonymous
u did it in 2 steps i did it in 1
anonymous
  • anonymous
Yup, It's quicker, but the numbers are much larger to work with...
anonymous
  • anonymous
same thing
anonymous
  • anonymous
z/-28+44 = 49 -28+44 [ z / -28+44 = 49 ] z = 49( -28+44 ) z = 784

:/
anonymous
  • anonymous
hmm i always do something wrong lol
anonymous
  • anonymous
I know, it's because you multiplied the whole equation by -28+44..
anonymous
  • anonymous
You're first meant to subtract 44 from 49
anonymous
  • anonymous
thats not incorrect
anonymous
  • anonymous
ooo i read it incorrectly
anonymous
