soz not 4y :S
(7/3x - 2/3x) + (5/6y-1/2y) + 9 (5/3x) + (5/6y - 3/6y) + 9 5/3x + 2/6y + 9 5/3x + 1/3 y + 9
Your second x term is incorrect, MissM.
peddani is correct
but 7-3+=4 not 5 :S
but it's 7-2, not 7-3 :)
oh i see i read the qs wrong :(
I need help with 3 more . Collect like terms 26x + 8 - 16x -6
Collect like terms 7p - p
Do you know what it means to collect like terms?
Yes you combine them i am just really bad at this
Collect like terms 2x +11x
Okay. Well, the first...let's rearrange it so it's easier to see. 26x - 16x + 8 - 6 Now, since 26 and 16 are both multiplied by x, you can add them together. And I assume you know how to add 8 and -6!
you just have to remember to carry the signs with the coefficients. Coefficient just means the number multiplied by the variable - from the first question, 26 and -16 are the coefficients of x.
alright i got that
so what did you get for 26x + 8 - 16x - 6?
wait so i add 26x + (-16x)
that is 0
oh unless the negative becomes a positive
Is it? drop the x, for now -> 26 + (-16)=?
it is 10
Yes. so you are left with 10x + 8 - 6 = ?
8-6 = 2, yes, but you need to keep the 10x. So the final answer will be 10x - 2
SORRY! 10x + 2
ohhhhh because you need to first collect the like terms! for instance this is like proportions
So, try your next one.
7p - p... Keep in mind this is the same as 7p - 1p
i know any letter "number" in algebra by its self is always 1
Okay...so what is the simplification of this problem?
the answer will be 6p?
Yes! What about your last one? 2x +11x ?
oh k its 13x
You got it! :)
thank you so much help
You are welcome. You can give me a medal as thanks! :)
: ) ill prob will post a another question if i run into trouble with my homework sheet so keep an out out for my user name!
I will, if I am here. Good luck!
oh look im back again well now im on the next step which is Solve using the additions principle
and the problem is x + 17 = 6
