Question

.25(8z - 4) = z + 8 - 2z

Answer 1

first distribute the .25

Answer 2

2z - .5 = -1z +8 ?

Answer 3

close, what is 4*.25 or 4(1/4)?

Answer 4

everything else in that step was correct

Answer 5

oHHH

Answer 6

so what do you get now?

Answer 7

2z - 1 = -1z + 8

Answer 8

correct, so the next step is to get the z's and the #'s on the same side

Answer 9

i subtracted 2z from both sides & got;
1 = -3z +8

Answer 10

then subtracted 8 from the answer & 8

Answer 11

i got -7 = -3z ?

Answer 12

close, there is one small thing wrong with your equation 1=-3z+8
if you fix this, and redo the steps in the same way, you will get a nice whole number for your answer. what do you think your mistake was?

Answer 13

To make it a little easier, I will put the two equations you typed next to each other.
2z-1=-z+8
1=-3z+8 <--Remember there is something wrong with this equation

Answer 14

i dont know, i cant figure it out.

Answer 15

ok, well you have the first equation:
2z-1=-z+8 ~~~you subtracted 2z from each side
-2z -2z ~~~ which gives you
-1=-3z+8 <-- this is correct. you simply forgot to leave the 1 as negative.

So using the correct equation: -1=-3z+8 what do you get as your answer now?

Answer 16

z = -3

Answer 17

that is soooooooo close!!! but if you have -3z=-9 what do you divide -9 by to get positive z all by itself?

Answer 18

wait i messed up on writing my reply, i got 3.

Answer 19

haha ok, but that is the correct answer!!! Good Job!!

Answer 20

thank you! could i ask for help on another problem really fast?

Answer 21

definitely!

Answer 22

the problem is -12h + 39 = -4h - 17
i know how to get the answer but do i add 4h to -4h to cancel it out or do i still subtract?

Answer 23

you would add 4h to both sides

Answer 24

okay i got h=7

Answer 25

That is correct!

Answer 26

okay, thank you!
