solve for Z: Y/4Z = X/W
2007-06-28 10:07:31 · update #1
Y / 4Z = X / W
==> cross multiply
4ZX = YW
==> divide by 4X
Z = YW / 4X
That's your answer: Z = YW / 4X

Here is your problem
y/4z=x/w
First,we've to make a domain so that the equation remains true always.
'z' & 'w' can not have a value zero for they are denominators,else the equation will be undefined.
By cross multiplying the equation,we get:
4xz=wy
Dividing both sides by 4x,we'll get:
z=1/4(wy/x); 'x' is different from zero

Y / (4Z) = X / W
cross multiply => YW = 4XZ
divide both sides by 4X => YW / (4X) = Z
or Z = (WY) / (4X)

You're notation is a bit confusing, but if I'm reading it correctly, it goes:
y / (4z) = x / w
y = (x4z) / w
z = (w y ) / (x4)

I have to spell it out:
Z equals x over w times 1 over y, with all of that over 4.
Hope that makes sense!

same as 4Z/Y = W/ X, so
4Z = WY/X, and
Z = WY/4X

WY=4ZX
WY/4X=Z
treat yourself

y/4z = x/w
yw = 4xz
z = (yw)/(4x)

W Y = 4 X Z
Z = (WY) / (4X)
