(3)+(0.2*(-12+5z))=z

Solution for (3)+(0.2*(-12+5z))=z equation:

Simplifying
(3) + (0.2(-12 + 5z)) = z
3 + (0.2(-12 + 5z)) = z
3 + ((-12 * 0.2 + 5z * 0.2)) = z
3 + ((-2.4 + 1z)) = z
3 + (-2.4 + 1z) = z

Remove parenthesis around (-2.4 + 1z)
3 + -2.4 + 1z = z

Combine like terms: 3 + -2.4 = 0.6
0.6 + 1z = z

Solving
0.6 + 1z = z

Solving for variable 'z'.

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

Add '-1z' to each side of the equation.
0.6 + 1z + -1z = z + -1z

Combine like terms: 1z + -1z = 0
0.6 + 0 = z + -1z
0.6 = z + -1z

Combine like terms: z + -1z = 0
0.6 = 0

Add '-0.6' to each side of the equation.
0.6 + -0.6 = 0 + -0.6

Combine like terms: 0.6 + -0.6 = 0.0
0.0 = 0 + -0.6

Combine like terms: 0 + -0.6 = -0.6
0.0 = -0.6

Simplifying
0.0 = -0.6

Combine like terms: 0.0 + 0.6 = 0.6
0.6 = -0.6 + 0.6

Combine like terms: -0.6 + 0.6 = 0.0
0.6 = 0.0
