try to solve it first
if you get equal sides then infinitely many solution example 4=4
if both sides are not equal then no solution like 9=7

- Nnesha

if you get x = something
then one solution

- Nnesha

\[\huge\rm \color{blue}{3x − 3x }\color{reD}{− 2 = −2}\]combine like terms

- DecentNabeel

3x − 3x − 2 = −2
no solution
add 2 on both sides
3x-3x=-2+2
0=0

- Nnesha

nice try ...

- Nnesha

but guess what

- anonymous

what

- Nnesha

what's your answer ?

- anonymous

no solution

- Nnesha

alright then.

- anonymous

is it right

- Nnesha

I believe you didn't read my first comment

- anonymous

wdy mean

@sweetburger can you check this out

3x-3x = ?

- anonymous

0

- Nnesha

so you get equal sides \[\huge\rm \color{blue}{\cancel{3x − 3x} }\color{reD}{− 2 = −2}\]
-2=-2 so answer is ?

- anonymous

o

- Nnesha

what's that ?

you got -2=-2 so which one is correct answer?

- anonymous

one solution

- DecentNabeel

so @Nnesha what is the value of x..
you say many solution

- anonymous

i am confused

- Nnesha

if you get equal sides then infinitely many solutions
if both sides are not equal then no solution

- Nnesha

you got -2=-2 both sides are equal so answer is ?

- DecentNabeel

only tell me what is the value of x..

- anonymous

so there is one solution

- Nnesha

no

- anonymous

it is zero

- Nnesha

x cancels out right
you get -2=-2 equal sides

- Nnesha

let me repeat t
if both sides are equal like 4=4 then your answer would be infinitely many solutions

- DecentNabeel

@Nnesha you mean no value of x..
you said previous comment in many solution..
so what solution

- anonymous

oh

- Nnesha

4=9 no solution
x= something , one solution
4=4 infinitely many solution

- Nnesha

so what do you think ?

- anonymous

many solutions

- Nnesha

thats right!

- anonymous

thank you

- Nnesha

Yw

- DecentNabeel

no the answer is..
no solution

- Nnesha

how is it no solution ?

- DecentNabeel

3x-3x=0
so that the variable is the cancle out

- Nnesha

okay you will get 0=0 so thats mean both sides are equal

- anonymous

soooo

- Nnesha

so what ?

- DecentNabeel

then solve it..
so what is the variable for solving..
there is no variable for sloving..
so there is no solution

- Nnesha

......

- Nnesha

repeating when you get equal sides 't the end then infinitely many solution
believe it or NOT

- DecentNabeel

not

- Nnesha

as you wish, sir

- DecentNabeel

AS you wsih @Nnesha expert

- Nnesha

you can tag some expert here i wouldn't mind ..

- DecentNabeel

yes i have no mind..
i clear the concept

- DecentNabeel

This solution could also be stated as "all real numbers" or "all reals" or "the whole number line"; expect some variation in lingo from one text to the next. Note that, if I had solved the equation by subtracting a 5 from either side of 5 + 4x = 5 + 4x to get "4x = 4x", I would have ended up with nothing other than another trivially-true statement. I could also have subtracted both 4x and 5 from both sides to get "0 = 0", but the solution would still be the same: "all x". Don't be surprised if, for "all real numbers" or "no solution" equations, you don't necessarily have the exact same steps as some of your fellow students. Since there are infinitely-many always-true equations (like "0 = 0") and infinitely-many nonsensical equations (like "3 = 4"), there will be many ways of arriving at these answers

- Nnesha

you can substitute x by any number you will get equal sides
\[\huge\rm 3(9)-3(9)-2=-2\]
or let plug in 2 \[\huge\rm 3(-2)-3(-2)-2=-2\]
both sides are e qual how can you say that there is no solution ?

- DecentNabeel

i think both are true..
some expert say no solution..
and some one is many

- Nnesha

well you can plug in any number you will get equal sides so thats means infinitely many solution

- DecentNabeel

@Nnesha expert you can see it

- Nnesha

so http://prntscr.com/7yn3yb solution is all x
thats mean any number can be x

- Nnesha

http://prntscr.com/7yn46i

- DecentNabeel

so the finally answer is..
this is no solution for this equation..
but many solution for all x

- DecentNabeel

@Nnesha are you clear

- Nnesha

wait what ?

- Nnesha

x can be any number
so infinitely many solution :=)

- DecentNabeel

yes i agree many solution for x..
but there is no solution for equation

- Nnesha

what do you mean ?
i already posted some example where we get equal sides so thats mean there are many solution for equation

- DecentNabeel

ohhhhhhhhhhhhhhhh

- DecentNabeel

as you wish

- Nnesha

as you wish ?
no
thats how it works *mathematically*
