%285%2F4%29u=1%2F12%2B%282%2F3%29u Start with the given equation.


12%28%285%2Fcross%284%29%29u%29=12%281%2Fcross%2812%29%2B%282%2Fcross%283%29%29u%29 Multiply both sides by the LCD 12 to clear any fractions.


15u=1%2B8u Distribute and multiply.


15u-8u=1 Subtract 8u from both sides.


7u=1 Combine like terms on the left side.


u=%281%29%2F%287%29 Divide both sides by 7 to isolate u.
