-14=5\left(2z-1\right)
Add 2 and 12 to get 14.
-14=10z-5
Use the distributive property to multiply 5 by 2z-1.
10z-5=-14
Swap sides so that all variable terms are on the left hand side.
10z=-14+5
Add 5 to both sides.
10z=-9
Add -14 and 5 to get -9.
z=\frac{-9}{10}
Divide both sides by 10.
z=-\frac{9}{10}
Fraction \frac{-9}{10} can be rewritten as -\frac{9}{10} by extracting the negative sign.
