Question

(x/100) + (y/66) = (3x+5y)/z. What is z?

Answer 1

first i would multiply both sides by z*100*66, that will clear fractions

Answer 2

So I would just be left with the variables?

Answer 3

On the right side.

Answer 4

I would say multiply all sides by z to get

\(\dfrac{x}{100}+\dfrac{y}{66} = \dfrac{3x+5y}{z}\)

\(\dfrac{x}{100}z+\dfrac{y}{66}z = \dfrac{3x+5y}{z}z\)

\(\dfrac{1}{100}xz+\dfrac{1}{66}yz = 3x+5y\)

Answer 5

Right?

Answer 6

I'm a little confused..

Answer 7

Hm.
