like a first step on the left side factorize out the x so what will get ?
OpenStudy (ihats1):
?? im at x+2nx=p-m is that correct? for the first step
OpenStudy (volleysappspbj16):
what he is saying is that mx and 2nx both share a factor of x so you can factor it out
x(m+2n)=p
jhonyy9 (jhonyy9):
yes Volley this is the first step right - nice job
OpenStudy (volleysappspbj16):
:)

OpenStudy (ihats1):
so do i subtract x and divide p?
OpenStudy (volleysappspbj16):
no
jhonyy9 (jhonyy9):
and now after this for can separate the x just divide both sides by (m+2n)
OpenStudy (volleysappspbj16):
you can't subtract x from x(m+2n) because they are being multiplied, instead you must do the opposite of multiplication and divide like jhony9 said
OpenStudy (ihats1):
so divide both sides?

no
OpenStudy (ihats1):
wait
OpenStudy (volleysappspbj16):

x
OpenStudy (ihats1):
?
OpenStudy (volleysappspbj16):

than what?
OpenStudy (volleysappspbj16):
or bad stuff will happen
OpenStudy (volleysappspbj16):
thats it
OpenStudy (volleysappspbj16):
x=p/(m+2n)
OpenStudy (ihats1):
x=p (m+2n)?

no
OpenStudy (volleysappspbj16):
you divided both sides by (m+2n)
OpenStudy (ihats1):
so divide by p?
OpenStudy (volleysappspbj16):
no
OpenStudy (volleysappspbj16):
the answer is x= p divided by (m+2n)

ok thank you
OpenStudy (volleysappspbj16):
uh hu
OpenStudy (triciaal):
here are the general guidelines
first put all the terms with the subject on one side of the equation and move everything else to the other side.
to move you do the inverse and whatever you do to one side of an equation you do to the other to keep the value.
simplify each side if you can.
now divide each side by the coefficient of the subject.
