z-0.2=2z

Solution for z-0.2=2z equation:

Simplifying
z + -0.2 = 2z

Reorder the terms:
-0.2 + z = 2z

Solving
-0.2 + z = 2z

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.

Add '-2z' to each side of the equation.
-0.2 + z + -2z = 2z + -2z

Combine like terms: z + -2z = -1z
-0.2 + -1z = 2z + -2z

Combine like terms: 2z + -2z = 0
-0.2 + -1z = 0

Add '0.2' to each side of the equation.
-0.2 + 0.2 + -1z = 0 + 0.2

Combine like terms: -0.2 + 0.2 = 0.0
0.0 + -1z = 0 + 0.2
-1z = 0 + 0.2

Combine like terms: 0 + 0.2 = 0.2
-1z = 0.2

Divide each side by '-1'.
z = -0.2

Simplifying
z = -0.2
