Combine like terms: -0.4z + 0.4z = 0.0
0.72 + 2.3z = 5.5 + 0.0
0.72 + 2.3z = 5.5

Add '-0.72' to each side of the equation.
0.72 + -0.72 + 2.3z = 5.5 + -0.72

Combine like terms: 0.72 + -0.72 = 0.00
0.00 + 2.3z = 5.5 + -0.72
2.3z = 5.5 + -0.72

Combine like terms: 5.5 + -0.72 = 4.78
2.3z = 4.78

Divide each side by '2.3'.
z = 2.07826087

Simplifying
z = 2.07826087
