you wanna get rid of any fractions by multiplying all the terms by their denominators. so the whole equation becomes: -5=15x-9. -15x=-4 15x=4 x=4/15

  • anonymous
So -1/3 . - 3/5 = 3/15 The fractions is what gets me. But thank you.
anonymous
  • anonymous
this is so you can cancel the -3 / 5

Ok so you multipy on both sides the -1/3
anonymous
  • anonymous
multiply it with a - 5/ 3
anonymous
  • anonymous
you have -1/3 = x - 3/5 it would be better to multiply it in 1 go and simplify
anonymous
  • anonymous
multiply with reciprocal of -3/5 it would be easier you could do -1/3 reciprocal but it would be more work
anonymous
  • anonymous
So either side is ok? I didn't know that. Thank you!
anonymous
  • anonymous
yup
anonymous
  • anonymous
:)
anonymous
  • anonymous
any other questions?
anonymous
  • anonymous
Yes I have another equation 3x = 2x + 7
anonymous
  • anonymous
since if you multiply for example a equation by -1 you have to do so to both sides you know that right?
anonymous
  • anonymous
No Im so lost right now.
anonymous
  • anonymous
o okies you know what this sign = means right?
anonymous
  • anonymous
equals yes lol
anonymous
  • anonymous
it means is equal to
anonymous
  • anonymous
the equation 3x=2x+7 it reads 3x is equal to 2x plus 7
anonymous
  • anonymous
so do you kinda understand what this is know
anonymous
  • anonymous
now*
anonymous
  • anonymous
how it works
anonymous
  • anonymous
Yes I know we have to combine like terms but when I did it I came up with the wrong answer
anonymous
  • anonymous
I came up with 1x
anonymous
  • anonymous
not like terms but equal amounts just think of it like this you got a 2 ml cups of water A and B they are supposed to be equal if you add 4 pints to cup A Will they still be equal? How will you make them equal? Add 4 pints to cup B right? what is the symbol of adding? its a plus sign + 4 pints
anonymous
  • anonymous
yes
anonymous
  • anonymous
is it more understandable?
anonymous
  • anonymous
a little so do i add the 2x to 3x or am I still off base?
anonymous
  • anonymous
2x = 3x + 7 what would be the easiest method try to make it simpler for you self yes , correct make the like terms dissapear
anonymous
  • anonymous
I did it like this: 3x = 2x + 7 -2x -2x
anonymous
  • anonymous
I know the answer is 7 from looking in the back of the book just can't figure out how to get the answer to 7
anonymous
  • anonymous
additive inverse of 2x is negative 2x do this on both sides
anonymous
  • anonymous
yes I did that
anonymous
  • anonymous
x cannot be negative
anonymous
  • anonymous
how would you get a positive x?
anonymous
  • anonymous
I"m not sure but I think the +3x -2x should egual a positive but that is 5x
anonymous
  • anonymous
umm you sure the problem was 2x = 3x + 7
anonymous
  • anonymous
not - 7
anonymous
  • anonymous
no the problem is 3x =2x + 7
anonymous
  • anonymous
answer is 7 but don't see how to get that answer.
anonymous
  • anonymous
okies here is what i get 3x = 2x +7 (-2 x) 3x = 2x + 7 + (-2x) additive inverse of 2x
anonymous
  • anonymous
can you figure the rest :)
anonymous
  • anonymous
yes thank you
anonymous
  • anonymous
anything else?
