1-k=5\left(-2k+1\right)
Variable k cannot be equal to \frac{1}{2} since division by zero is not defined. Multiply both sides of the equation by -2k+1.
1-k=-10k+5
Use the distributive property to multiply 5 by -2k+1.
1-k+10k=5
Add 10k to both sides.
1+9k=5
Combine -k and 10k to get 9k.
9k=5-1
Subtract 1 from both sides.
9k=4
Subtract 1 from 5 to get 4.
k=\frac{4}{9}
Divide both sides by 9.
