Answer: 19.56z - 9
Step-by-step explanation: Hello! Here are the steps to solve this problem:
14.33z - 3 - (6 - 5.23z).
Firstly, you have to use the distributive property and distribute -1 to the parentheses using PEMDAS, Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
14.33z - 3 + -1(6 - 5.23z)
14.33z - 3 + (-6 + 5.23z)
14.33z + (-3) + (-6) + (5.23z)
14.33z + (5.23z) + (-3) + (-6)
(14.33z + 5.23z) + (-3 - 6)
19.56z + (-3 - 6)
19.56z + (-9)
19.56z - 9.
