Answer:
x= -1
Step-by-step explanation:
1. First, you need to combine like terms. Constants with constants and variables with variables. Since there is only one variable, there is nothing to combine it with so nothing happens to it. The constants, on the other hand, can combine.
2. You have to subtract 28 from 28 and 14 so that +28 can cancel out on the left side and combine on the right.
3. That will leave you with 14x= -14.
4. Now you need to get x on its own so you need to divide 14 (opposite of multiplication to cancel out) on both sides.
5. That will leave you with x= -1. That is your final answer.

Answer:
6 hours
Step-by-step explanation:
Let the labor hours be x.
The bill comprises of parts cost plus labor cost. Labor cost is hours times the cost per hour. Then we have equation:
- 265 + 48x = 553
- 48x = 553 - 265
- 48x = 288
- x = 288/48
- x= 6
So the answer is 6 hours.
