Note: 5%261%2F6=31%2F6 and 2%263%2F4=11%2F4


So the equation also looks like: 31%2F6-u=11%2F4


31%2F6-u=11%2F4 Start with the given equation.


12%2831%2Fcross%286%29-u%29=12%2811%2Fcross%284%29%29 Multiply both sides by the LCD 12 to clear any fractions.


62-12u=33 Distribute and multiply.


-12u=33-62 Subtract 62 from both sides.


-12u=-29 Combine like terms on the right side.


u=%28-29%29%2F%28-12%29 Divide both sides by -12 to isolate u.


u=29%2F12 Reduce.

Answer:

So the answer is u=29%2F12 which approximates to u=2.417.
