u\times 12=1800000-100u
Multiply both sides of the equation by 100.
u\times 12+100u=1800000
Add 100u to both sides.
112u=1800000
Combine u\times 12 and 100u to get 112u.
u=\frac{1800000}{112}
Divide both sides by 112.
u=\frac{112500}{7}
Reduce the fraction \frac{1800000}{112} to lowest terms by extracting and canceling out 16.
