combine like terms
-3x + x = ?
7 - 4 = ?
now put them together and what do you get ?
OpenStudy (anonymous):
3?
OpenStudy (anonymous):
don't forget to do the x terms
OpenStudy (anonymous):
can you explain it more?
OpenStudy (anonymous):

-3x2
OpenStudy (anonymous):
no...-3x + x -2x
do you understand ?
OpenStudy (anonymous):
oops..-3x + x = -2x
OpenStudy (anonymous):
we have to find
???

and 7 - 4 = 3
so now you have -2x + 3
OpenStudy (anonymous):
so what do i do now?
OpenStudy (anonymous):
x=3/2
OpenStudy (anonymous):
thats the answer...-2x + 3
OpenStudy (anonymous):

i think we have to find value of x
OpenStudy (anonymous):
there is no equal sign, therefore, all you can do is simplify to 2x - 3
OpenStudy (anonymous):
oops..-2x + 3
OpenStudy (anonymous):
or 3 - 2x
OpenStudy (anonymous):
there is np equal sign but we can put above equation equal to zero. and then we can caloculate vale of 'x'

OpenStudy (anonymous):
7 - 4 = 3
-3x - x = -2x
put it together and we have 3 - 2x, which is the same as -2x + 3.
OpenStudy (anonymous):
thank you kelliegurl33
OpenStudy (anonymous):
-3x + x = -2x....sorry about that
OpenStudy (anonymous):
its ok
OpenStudy (anonymous):
