Step-by-step explanation:
P=2a+b
Solve for a.
Divide both sides by 2 to isolate a.
P=2a+b
P/2=a+b/2
When you rewrite the equation, it becomes:
a=P/2-b/2 (The sign changes from a positive to a negative because you need to move P/2 to the other side to get a to one side)
Therefore, your final answer is: a=P/2-b/2

Therefore, the number of hours is substitued by x and it is right next to the amount they charge for each hour. To find what each company charges, you must sum up what they charge and what they charge per hour, times the hours they will have to work on it( which is unknown and by x).
