13-7\left(k-1\right)=9k-6
Multiply both sides of the equation by 3.
13-7k+7=9k-6
Use the distributive property to multiply -7 by k-1.
20-7k=9k-6

20-7k-9k=-6
Subtract 9k from both sides.
20-16k=-6
Combine -7k and -9k to get -16k.
-16k=-6-20
Subtract 20 from both sides.
-16k=-26
Subtract 20 from -6 to get -26.
k=\frac{-26}{-16}
Divide both sides by -16.
k=\frac{13}{8}
Reduce the fraction \frac{-26}{-16} to lowest terms by extracting and canceling out -2.
