  • LynFran
is there a typo with the first problem..?? 7+8x+-1 ??
anonymous
  • anonymous
no its really looks like -1=7+8x
LynFran
  • LynFran
thats a better view...anyways... we need to solve for x so we can take 7 frm both sides of the equation we get -1-7=7-7+8x simplify we get -1-7=8x wats -1-7 equals to?
anonymous
  • anonymous
-8
LynFran
  • LynFran
good so -8=8x
LynFran
  • LynFran
we now divide both sides by 8 to solve for x
LynFran
  • LynFran
whats did u get for x?
anonymous
  • anonymous
-1?
LynFran
  • LynFran
correct
anonymous
  • anonymous
I kept on getting -8
LynFran
  • LynFran
-8/8=-1
LynFran
  • LynFran
-8=8x -8/8=8x/8 -1=x
anonymous
  • anonymous
i get it
LynFran
  • LynFran
ok
anonymous
  • anonymous
how would you do 10+h/3=1
LynFran
  • LynFran
first subtract 10 frm both sides of the equation so 10-10+h/3=1-10 simplify we get..?
anonymous
  • anonymous
0+h/3=-9?
LynFran
  • LynFran
yes h/3=-9
LynFran
  • LynFran
now we multiply both sides of the equation by b ...that way we can get h alone on the left side of the equation
LynFran
  • LynFran
by 3"
LynFran
  • LynFran
multiply both sides of the equation by 3
anonymous
  • anonymous
-9 times 3 equals -27
LynFran
  • LynFran
yes thats what h= to
anonymous
  • anonymous
-27?
LynFran
  • LynFran
yep
LynFran
  • LynFran
the next equation is done the same way like the previous 1 above m/6+5=26 whats the first step??
anonymous
  • anonymous
subtract 5 from each side
LynFran
  • LynFran
correct then what??
anonymous
  • anonymous
multiply 6 to each side
anonymous
  • anonymous
I got 126
LynFran
  • LynFran
me too
anonymous
  • anonymous
what about the next equation? the subtraction sign got me
LynFran
  • LynFran
-5x-2=13 we can add 2 to both sides of the equation reason y... -2+2=0
LynFran
  • LynFran
so we have -5x=13+2 whats next??
anonymous
  • anonymous
13+2 equals 15?
LynFran
  • LynFran
yes -5x=15 now how can we get the x term alone ...since -5 is being multiple to x giving -5x
LynFran
  • LynFran
whats the opposite of multiplication?
anonymous
  • anonymous
division
LynFran
  • LynFran
yes we divide both sides of the equation by.... ??
anonymous
  • anonymous
5?
LynFran
  • LynFran
shd be -5
LynFran
  • LynFran
if we divide by 5 then we have -x=15/5
anonymous
  • anonymous
so x equals -3
LynFran
  • LynFran
correct
anonymous
  • anonymous
Could you help me with -1=4+x/3?
LynFran
  • LynFran
what the first step...do u know..?
anonymous
  • anonymous
subtract 4 from each side
LynFran
  • LynFran
correct
anonymous
  • anonymous
so, x/3=-5
LynFran
  • LynFran
yes now whats the next step?
anonymous
  • anonymous
multiply 3 to each side
LynFran
  • LynFran
correct
anonymous
  • anonymous
so, x=-15?
LynFran
  • LynFran
yep
anonymous
  • anonymous
Thank you very much for helping me!
