Step-by-step explanation:
![\sf{12 - 5i + ( - 3 + 4i)}](https://tex.z-dn.net/?f=%20%5Csf%7B12%20-%205i%20%2B%20%28%20-%203%20%2B%204i%29%7D)
When there is a ( + ) in front of an expression in parentheses, there is no need to change the sign of each term. That means, the expression remains the same. Just remove the parentheses
![\longrightarrow{ \sf{12 - 5i - 3 + 4i}}](https://tex.z-dn.net/?f=%20%5Clongrightarrow%7B%20%5Csf%7B12%20-%205i%20-%203%20%2B%204i%7D%7D)
Collect like terms
![\longrightarrow{ \sf{ 12 - 3 - 5i + 4i}}](https://tex.z-dn.net/?f=%20%5Clongrightarrow%7B%20%5Csf%7B%2012%20-%203%20-%205i%20%2B%204i%7D%7D)
Subtract 3 from 12
![\longrightarrow{ \sf{9 - 5i + 4i}}](https://tex.z-dn.net/?f=%20%5Clongrightarrow%7B%20%5Csf%7B9%20-%205i%20%2B%204i%7D%7D)
Collect like terms
![\longrightarrow{ \sf{9 - i}}](https://tex.z-dn.net/?f=%20%5Clongrightarrow%7B%20%5Csf%7B9%20-%20i%7D%7D)

Answer:
The electrician charges $46 per hour
Step-by-step explanation:
we know that
An electrician charges $322 for 7 hours of work
so
using proportion
Find out how much does the electrician charge per hour
Let
x ----> the charge per hour
![\frac{322}{7}\frac{\$}{h}=\frac{x}{1}\frac{\$}{h}\\\\x=322/7\\\\x=\$46](https://tex.z-dn.net/?f=%5Cfrac%7B322%7D%7B7%7D%5Cfrac%7B%5C%24%7D%7Bh%7D%3D%5Cfrac%7Bx%7D%7B1%7D%5Cfrac%7B%5C%24%7D%7Bh%7D%5C%5C%5C%5Cx%3D322%2F7%5C%5C%5C%5Cx%3D%5C%2446)
therefore
The electrician charges $46 per hour
