Question

Hi

I have to rearrnge the following to make y the subject..

x = 3 - 2y / 6

I get the first part do

x 3, - 2, and / 6.

Undo

x 6, + 2, and / 3

then multiply by 6 so,

6x = 3 - 2y

add 2 to both sides,

6x + 2 = 3
the divide both sides by 3

6x + 2 = y
-------
3

so y = 6x - 2
-------
3
is this the right final answer ???

i am not sure if this is right .. can anyome check this for me..

If the answer is wrong please tell me where I have mis-calculated

Thank you !!!!!!!! :-)

Answer 1

Isn't the 3-2y supposed to be in parentheses? Otherwise, 2y/6 should have been written y/3.

If x = (3 -2y)/6, then
6x = 3 - 2y
2y = 3 - 6x
y = (3/2) -3x

Answer 2

I understand..and thank you for your help !!
