12k-3\left(3\times 4+1\right)=2\times 12+5
Multiply both sides of the equation by 12, the least common multiple of 4,12.
12k-3\left(12+1\right)=2\times 12+5
Multiply 3 and 4 to get 12.
12k-3\times 13=2\times 12+5
Add 12 and 1 to get 13.
12k-39=2\times 12+5
Multiply -3 and 13 to get -39.
12k-39=24+5
Multiply 2 and 12 to get 24.
12k-39=29
Add 24 and 5 to get 29.
12k=29+39
Add 39 to both sides.
12k=68
Add 29 and 39 to get 68.
k=\frac{68}{12}
Divide both sides by 12.
k=\frac{17}{3}
Reduce the fraction \frac{68}{12} to lowest terms by extracting and canceling out 4.
