12-3\left(2u+3\right)=4\left(2-5u\right)-36u
Multiply both sides of the equation by 12, the least common multiple of 4,3.
12-6u-9=4\left(2-5u\right)-36u
Use the distributive property to multiply -3 by 2u+3.
3-6u=4\left(2-5u\right)-36u
Subtract 9 from 12 to get 3.
3-6u=8-20u-36u
Use the distributive property to multiply 4 by 2-5u.
3-6u=8-56u
Combine -20u and -36u to get -56u.
3-6u+56u=8
Add 56u to both sides.
3+50u=8
Combine -6u and 56u to get 50u.
50u=8-3
Subtract 3 from both sides.
50u=5
Subtract 3 from 8 to get 5.
u=\frac{5}{50}
Divide both sides by 50.
u=\frac{1}{10}
Reduce the fraction \frac{5}{50} to lowest terms by extracting and canceling out 5.
