Simplifying
0.3(3z + 6) + 2.6 = 0.4(3z + -4)

Reorder the terms:
0.3(6 + 3z) + 2.6 = 0.4(3z + -4)
(6 * 0.3 + 3z * 0.3) + 2.6 = 0.4(3z + -4)
(1.8 + 0.9z) + 2.6 = 0.4(3z + -4)

Reorder the terms:
1.8 + 2.6 + 0.9z = 0.4(3z + -4)

Combine like terms: 1.8 + 2.6 = 4.4
4.4 + 0.9z = 0.4(3z + -4)

Reorder the terms:
4.4 + 0.9z = 0.4(-4 + 3z)
4.4 + 0.9z = (-4 * 0.4 + 3z * 0.4)
4.4 + 0.9z = (-1.6 + 1.2z)

Solving
4.4 + 0.9z = -1.6 + 1.2z

Solving for variable 'z'.

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

Add '-1.2z' to each side of the equation.
4.4 + 0.9z + -1.2z = -1.6 + 1.2z + -1.2z

Combine like terms: 0.9z + -1.2z = -0.3z
4.4 + -0.3z = -1.6 + 1.2z + -1.2z

Combine like terms: 1.2z + -1.2z = 0.0
4.4 + -0.3z = -1.6 + 0.0
4.4 + -0.3z = -1.6

Add '-4.4' to each side of the equation.
4.4 + -4.4 + -0.3z = -1.6 + -4.4

0.0 + -0.3z = -1.6 + -4.4
-0.3z = -1.6 + -4.4

Combine like terms: -1.6 + -4.4 = -6
-0.3z = -6

Divide each side by '-0.3'.
z = 20

Simplifying
z = 20
