So you first want to move all variables to one side.
2x = 1/8 + 4x
So perform the opposite of each operation to move it.
2x - 4x = 1/8 + 4x - 4x
-2x = 1/8
And then just divide both sides by -2
-2x / -2 = 1/8 / -2
x = -1/16
The answer is 102 because you subtract 180-78.

Time = Distance/Speed
Let d represent the distance from home to the resort in miles.
Time To Resort = d/48
Time To Home = d/40
Total Time = Time To Resort + Time To Home
11 = d/48 +d/40 . . . . . . . . . . substitute known values & expressions
.. = d*(40 +48)/(40*48) . . . . add fractions
.. = d*11/240 . . . . . . . . . . . . . simplify
11*(240/11) = d . . . . . . . . . . . multiply by the inverse of the coefficient of d
240 = d
The Gomez family traveled 240 miles from their house to the resort.
