z-0.1=2z

Solution for z-0.1=2z equation:

Simplifying
z + -0.1 = 2z

Reorder the terms:
-0.1 + z = 2z

Solving
-0.1 + 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.
-0.1 + z + -2z = 2z + -2z

Combine like terms: z + -2z = -1z
-0.1 + -1z = 2z + -2z

Combine like terms: 2z + -2z = 0
-0.1 + -1z = 0

Add '0.1' to each side of the equation.
-0.1 + 0.1 + -1z = 0 + 0.1

Combine like terms: -0.1 + 0.1 = 0.0
0.0 + -1z = 0 + 0.1
-1z = 0 + 0.1

Combine like terms: 0 + 0.1 = 0.1
-1z = 0.1

Divide each side by '-1'.
z = -0.1

Simplifying
z = -0.1
