Question
9=-21-1110z
Solve the equation
z=-\frac{1}{37}
Alternative Form
z=-0.\dot{0}2\dot{7}
Evaluate
9=-21-1110z
Swap the sides of the equation
-21-1110z=9
Move the constant to the right-hand side and change its sign
-1110z=9+21
Add the numbers
-1110z=30
Change the signs on both sides of the equation
1110z=-30
Divide both sides
\frac{1110z}{1110}=\frac{-30}{1110}
Divide the numbers
z=\frac{-30}{1110}
