5\left(2c-1\right)=20\times 2
Multiply both sides by 2.
10c-5=20\times 2
Use the distributive property to multiply 5 by 2c-1.
10c-5=40
Multiply 20 and 2 to get 40.
10c=40+5
Add 5 to both sides.
10c=45
Add 40 and 5 to get 45.
c=\frac{45}{10}
Divide both sides by 10.
c=\frac{9}{2}
Reduce the fraction \frac{45}{10} to lowest terms by extracting and canceling out 5.
