More Practice Worksheet DUE WEDNESDAY 11/7/07. If you aren't sure if the factored to expanded form is correct make the rectangle model to check. Likewise if you aren't sure if the expanded to factored form is correct then use FOIL/distribute to check.

Do we put the answer in our note book for the worksheet?
this is denn my nickname is eskape
"eskape"..OMG..whatever..
i don't really understand what we were supposed to do on the MORE PRACTICE WORKSHEET
well i know how to do the first parts
but on the Set 1-Set 4 part is kind of confusing
what part do yiu do first for step 3
Do we put the answers from the work sheet into our math book?????

BRANDON, REMEMBER ONLY ALIAS OR YOUR FIRST NAME ONLY! (DUH!)
You can do the work either in your tablet or if it fits on that handout. I put a link up for "substitution method." I'm not sure if it will help.
The top two parts should be okay to do, since it is review.
For the bottom section with the two sets of equations do as it says. Solve for the first equation, in terms of the variable designated, then substitute the equation that you get into the second one.
So for set 1: Solve for x in Equation 1. Equation 1 should look like
x = ......something with y on the right.
In Equation 2, substitute
x = .....something with y on the right in place of x.
So 4y-3(what you got for x = something with y on the right) equals 1. Your final answer should be y =.
Let me know if that works.
Im stuck on the last one of the wkst. Can u help me?
i tried substatuting but i couldn't pull off an answer that fitz
nvr mind...i got it...

you could have said that all in one post.
Set 4: Solve for y in Equation 1 by doing a one-step. Y = -2x.
substitute and solve for x in Equation 2.
Equation 2: 2x - y = 1
2x-(-2x) = 1. You need to do the rest.
For Set 3 on the first part I got
X=.5+9Y
For part to do I put it like (.5+9Y)-4Y Or .5+9Y-4Y

solve for y in Equation 1. I would add 9y to both sides so that it is a positive value. the equation changes to 2x = 9y +1. From here solve for x by doing a two-step equation. You'll end up with y = something with fractions. Substitute this equation in place of y in the second equation. In solving for x you should get a whole number. This one is a bit more of a challenge.
