is that all of the equation?
Ineedhelpfast12
  • Ineedhelpfast12
yes

I don't think you can solve, but rather just simplify
Ineedhelpfast12
  • Ineedhelpfast12
how though
anonymous
  • anonymous
does it say if x equals anything?
Ineedhelpfast12
  • Ineedhelpfast12
11\[\frac{ 11 }{ 15}x\]?
Ineedhelpfast12
  • Ineedhelpfast12
no it just says solve for x

interesting, I'll tag someone @ccieux

***How do you solve for this equation? *** an equation *always* has an = sign where is your equal sign?
Ineedhelpfast12
  • Ineedhelpfast12
Fine how do you solve the PROBLEM?

@Nnesha help please
jdoe0001
  • jdoe0001
EQUATions "equate" to something so... you don't really have to "solve" anything per se
jdoe0001
  • jdoe0001
as phi said, there's no = sign
Ineedhelpfast12
  • Ineedhelpfast12
anybody out there speak english? I do not understand what jdoe0001 means
anonymous
  • anonymous
looks to me like a cross multiplication problem
zzr0ck3r
  • zzr0ck3r
@jdoe0001 is saying that in order to solve for \(x\) we need an equals sign. You just gave an expression, not an equation.
Ineedhelpfast12
  • Ineedhelpfast12
but it is an addition problem
jdoe0001
  • jdoe0001
hmmm
Ineedhelpfast12
  • Ineedhelpfast12
I am not trying to solve for x. I just need to simplify x/3+2/5
anonymous
  • anonymous
cross multiply then add, but i get what you guys are saying about their not being an equals sign =/

This is only Algebra 1 people. What does x6 stand for?

\(\bf \cfrac{x}{3}+\cfrac{2}{5}\implies \cfrac{}{LCD=15}\implies \cfrac{(15\div 3)x+(15\div5)2}{15}\)
zzr0ck3r
  • zzr0ck3r
\[\dfrac{x}{3}+\dfrac{2}{5}=\dfrac{5x}{5*3}+\dfrac{2*3}{5*3}=\dfrac{5x+6}{15}\]
Ineedhelpfast12

How about another question?

hopefully it makes sense :)

  • Ineedhelpfast12
that is a t
zzr0ck3r
  • zzr0ck3r
do you see how we simplified before?
Ineedhelpfast12
  • Ineedhelpfast12
no
zzr0ck3r
  • zzr0ck3r
\(\dfrac{a}{b}+\dfrac{c}{d}=\dfrac{ad+cb}{bd}\)
Ineedhelpfast12
  • Ineedhelpfast12
ok
zzr0ck3r
  • zzr0ck3r
for you \[a=x, b=y, c=2, d=t\]
Ineedhelpfast12
  • Ineedhelpfast12
so is it|dw:1439250477962:dw|
zzr0ck3r
  • zzr0ck3r
But you must realize we are not solving anything here, we are just simplifying.
zzr0ck3r
  • zzr0ck3r
yep
Ineedhelpfast12
  • Ineedhelpfast12
ok
Ineedhelpfast12
  • Ineedhelpfast12
a couple more
zzr0ck3r
  • zzr0ck3r
do the same thing...
zzr0ck3r
  • zzr0ck3r
I will tell you if you have the right answer

what would be the lcd?
Ineedhelpfast12
  • Ineedhelpfast12
80
zzr0ck3r
  • zzr0ck3r
40
zzr0ck3r
  • zzr0ck3r
sec
Ineedhelpfast12
  • Ineedhelpfast12
oh ya
zzr0ck3r
  • zzr0ck3r
\[\frac{2t}{8xy}+\dfrac{4tx}{10y}\] We want the denominator to be the same, lcm(8,10)=40 and we are missing an x on the right side \[\dfrac{5*2*t}{4*x*y}+\dfrac{4*4*t*x}{4*10*y*x}\]
Ineedhelpfast12
  • Ineedhelpfast12
me no get it
anonymous
  • anonymous
did yall solve it?
Ineedhelpfast12
  • Ineedhelpfast12
no we did not
