You can
put this solution on YOUR website! 2xy + x = 12 Please solve for y.
Show steps. thank you.
Subtract x from both sides:
2xy + x = 12
- x - x
----------------
2xy = 12 - x
Divide both sides by 2x
2xy 12 - x
----- = --------
2x 2x
1
2xy 12 - x
----- = -------
2x 2x
1
12 - x
y = -------
2x
That's it! Warning:
Don't do any cancelling
in this stage because the
numerator contains a
subtraction!
You can leave the answer
that way. Or else you
can separate it into two
fractions like this
first:
12 x
y = ---- - ----
2x 2x
And then you can cancel the
2 into the 12 in the first
fraction and cancel the x's
in the second fraction:
6 1
12 x
y = ---- - ----
2x 2x
1 1
6 1
y = --- - ---
x 2
Either answer is perfectly correct.
They are equivalent even though they
don't look the same. Use this one
12 - x
y = -------
2x
if you want y to equal to just one
fraction. Or use this one
6 1
y = --- - ---
x 2
if you don't mind having two
separate fractions. Either way
is correct, just don't try to
cancel without first separating
into two fractions.
