The equation would be
544 = 265 + 48x

The first step is to subtract 265 from both sides.
279 = 48x

The next step is to divide by 48 on both sides.
x=5.8125

That means that the mechanic worked for 5.8125 hours.

The final bill is $544
The parts is a one time bill of $265
The labor is $48 per hour, and lets call the hours 'h'

So we can make the equation as:

544 = 265 + 48h

Subtract 265 n both sides

279 = 48h

Divide by 48 on both sides

h = 5.8125

So the number of hours of labor spent repairing the car is 5.8125.
