hey!

25-3x=-8

firstly....you bring together the "like" terms together....so bring the "-8" over the equals sign changing it to "+8"....and bring the "-3x" over to the other side changing it to "+3x" or 3x

this looks like...

25 + 8 = 3x

get it?

------------------------------------------------------

now you solve the first addition part...

33 = 3x
------------------------------------------------------

next...you bring over the "3" beside the "33"...making the multiplication part into a division...(just remember the rule....change the side? then change the sign) =D

this looks like...

33/3 = x
11 = x

--------------------------------------------------

CHECKING:

25 - 3 x 11 = -8

--------------------------------------------------

hope you understand it now!
btw...yes im willing to help u with anymore questions like these ur stuck on...
can you post you email address and i can help u through msn?

=D
have a nice day!

25-3x=-8
-3x=-8-25
-3x=-33
x=-33/-3
x=11
2008-12-05 1:36 pm
25 - 3x = -8
25 + 8 = 3x
33 = 3x
33/3 = 3x/3
11 = x
x = 11

Keep em coming.

33 = 3x
x = 11
2008-12-05 1:34 pm
25-3x=-8
3x=33
x=11

25+8=3x so 3x = 33 and x=11, Simple it is.

25 - 3x = -8 ----> -3x = - 8 - 25 = -33 Therefore x = -33/-3 = 11
2008-12-05 1:38 pm
25 - 3x = -8
-3x = -8 - 25
-3x = -33
x = -33/-3
x = 11
2008-12-05 1:36 pm
25-3x=-8 (given)
3x=33 (add 8 and 3x to both sids)
x=11 (divide both sides by 3)
