3x+7=2x solve

OpenStudy (lgbasallote):

try subtracting both sides by 2x what do you get?

OpenStudy (anonymous):

2x-7 or 2x-3x

OpenStudy (lgbasallote):

it's 3x - 2x

OpenStudy (anonymous):

3x+7=2x 3x-2x+7=2x-2x What do you get?

OpenStudy (anonymous):

1x+7

OpenStudy (anonymous):

you forgot something.

OpenStudy (lgbasallote):

you only want x so what do you do?

OpenStudy (anonymous):

minus 1x from 1x and 7

OpenStudy (anonymous):

then what do you get?

OpenStudy (lgbasallote):

no no..you want x..you dont want to cancel x! :(

OpenStudy (anonymous):

oh you divide

OpenStudy (anonymous):

You are confused because you didn't write the whole equation down. Lets start again 3x-2x+7=2x-2x what does that become? Write it down.

OpenStudy (anonymous):

help

OpenStudy (anonymous):

just type the answer I dont understand what you wrote.

OpenStudy (anonymous):

1x+7

OpenStudy (anonymous):

hello romero

OpenStudy (anonymous):

That is close but you are missing something.

OpenStudy (anonymous):

tell me what i am missing

OpenStudy (anonymous):

romero

OpenStudy (anonymous):

1x+7=0

OpenStudy (anonymous):

you want to get x by itself so what do you do in order to do that? Subtract 7 from both sides.

OpenStudy (anonymous):

x = -7

OpenStudy (anonymous):

ok 1x=-7

OpenStudy (anonymous):

@Amberley Wow thank you for ruining this.

OpenStudy (anonymous):

leave amberley i dont want answers i want to learn how to do it

OpenStudy (anonymous):

yay you did it. Anyways x1 is the same as saying 1*x=x so it's x=-7

OpenStudy (anonymous):

7p-6=-4p

OpenStudy (anonymous):

good job. Sorry for giving you a hard time. If you have more questions Ill help you faster. hehe

OpenStudy (anonymous):

it ok i need the hard time

OpenStudy (anonymous):

umm ok well easiest thing you can do is add 4p to both sides. What do you get then?

OpenStudy (anonymous):

nvm it is a positive 4 srry

OpenStudy (anonymous):

oh ok then you subtract 4p instead

OpenStudy (anonymous):

3p-6=0

OpenStudy (anonymous):

great now you want p by itself so you add 6 to both sides. This will cancel the 6 from the left side.

OpenStudy (anonymous):

then 3p=6 right

OpenStudy (anonymous):

p=3

OpenStudy (anonymous):

Close you have to divide 3 to both sides. 3p/3=6/3 p=6/3 p=2

OpenStudy (anonymous):

oh wrong division
