2(3x+6)=3(4x-2) solve pls

OpenStudy (bahrom7893):

6x + 12 = 12x - 6, divide everything by 6 x + 2=2x - 1 x-2x = -1-2 -x = -3 x=3

where will i click it? do u know how to check?

OpenStudy (bahrom7893):

plug in x =3 back into original: 2(3*3+6) = 3(4*3-2) 2(9+6) = 3(12-2) 2*15 = 3 * 10 30 = 30 so the answer is correct and you can click Good Answer on the upper right corner of my answer.. all the way to the right of group star.

thank you so much for the help. but i have 1more. can you solve it again? 3(y-4)+3(y-2)

OpenStudy (bahrom7893):

is equal to what?

OpenStudy (anonymous):

3(y-4)+3(y-2)0

OpenStudy (anonymous):

3(y-4)=3(y-2)

OpenStudy (bahrom7893):

did you mean: 3(y-4)+3(y-2)=0, or 3(y-4)=3(y-2)

OpenStudy (anonymous):

3(y-4)=3(y-2) this one

OpenStudy (bahrom7893):

okay so: 3y - 12 = 3y - 6 3y-3y = -6 + 12 0 = 6, this is not true, so there are no solutions...

ok. thank you
