0.5+0.3y=0.7y=0.3

OpenStudy (anonymous):

Are you looking for y?

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

Okay hold on...

OpenStudy (anonymous):

K

OpenStudy (anonymous):

Okay so what do you believe you should do first?

OpenStudy (anonymous):

Subtract 0.7

OpenStudy (anonymous):

Okay...You always do the opposite :P What did you get?

OpenStudy (anonymous):

0.4

OpenStudy (anonymous):

Okay..Um is that =0.3 suppose to be ther because it's throwing me off completely lol

OpenStudy (anonymous):

Oh its subtract 0.3

OpenStudy (anonymous):

haha that's fine :P Everyone makes mistakes. Let me resolve this please.

OpenStudy (anonymous):

Ok

OpenStudy (anonymous):

Change it around to: 0.5 + 0.3y = -0.3 + 0.7y

OpenStudy (anonymous):

Now solve for y...

OpenStudy (anonymous):

Add '-0.7y' to each side of the equation. 0.5 + 0.3y + -0.7y = -0.3 + 0.7y + -0.7y

OpenStudy (anonymous):

Do you know how to combine like terms?

OpenStudy (anonymous):

Yes I think

OpenStudy (anonymous):

Okay do you wanna give it a shot

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

Okay...

OpenStudy (anonymous):

0.5+1.0y=0.3+1.4y

OpenStudy (anonymous):

Yes:P I actually seen I had made a mistake in that lol...Now you add what number to both sides?

OpenStudy (anonymous):

Is it 1.4y

OpenStudy (anonymous):

No you have to add -0.5 to both sides :P

OpenStudy (anonymous):

1.0y=0.8+1.4y
