What is x when 3x+20=2x-10

-30

dont just give an answer that is useless.... write a few words how to get it

her ques just asks about x.

its better to explain things 3x+20=2x-10 5x+20=-10 you subtract 20 by -10 you get -30 5x=-30 then you divide 5 by negative 30 and you get x=-6 basically the answere above is wrong

oh and you add the x`s

jackie actually you are wrong :(

and actually its positive six two negatives equal a positive

my bad

3x+20=2x-10 3x-2x=x not 5x

but it is better to explain! I do lot of mistakes I guess

you don subtract you add them the only time you subtract is if it has -

3x + 2x

oh forget it haha thats the way i was taught but we all do things differently eventually one of us is right

no 3x+20=2x-10 you want to have all the x-s in one side, so you can subtract 3x to get rid of 3x from the left or subtract 2x to get rid of 2x from the right side. 3x+20=2x-10 3x-2x+20=2x-2x-10 x+20=-10 x=-30

I thought you always add the x`s my mistake your good at this XP

I am doing maths at university so it would be bad if I wouldnt be able to do this :-)

But isnt it positive since you subtract 20 from from negative 10 you`ll get 30

-10-20=?

a negative and a negative equalls a positive

a negative times a negative is a positive

or 2 negative signs give positive, for example 10-(-5)=15

but -10-20=-30 there is no trick here

but since its +20 you subtract it on the other side with -10 = positive thirty

are you ok until x+20=-10 ?

Yes sir

:-) if you add 20 to both sides x+20+20=-10+20 x+40=10 did this help?

you subtract 20 but what im saying is isnt a gegative and a negative equLL a positive

not when you subtract

you subtract 20 to get rid of it on one side

yeah x+20-20=-10-20 x=-10-20=-30

but the thing is two negatives equall a positive

if you are in 10 dollar debt and they take away 20 dollars from you, than you will be in 30 dollar debt

right or wrong cuz im so about to give up

depends :)

-9*-2=18 5-(-10)=15 -5-10=-15 5-10=-5

hmm why don you help me on my ? your good at math and I give up way to confusing.

well I know that I am the 1% of the population that likes maths

then help me out yeah its still unanswered

which one the - - =+ ?

no click unanswered ? and its the baseball one

3x+20=2x-10 becomes 3x-2x= -30 then x(1)=-30 so x= -30
