Answer:
the error is in step 2.
0.25x was added to -0.75x with an incorrect result of +0.50x.

The incorrect step is ...
Step 2: negative 1.50 = 0.50 x
This is the result of an attempt to add 0.25x to both sides of the equation. The correct step would be ...
-1.50 -0.25x = -0.75x . . . . . . . result from Step 1
-1.50 -0.25x +0.25x = -0.75x +0.25x . . . . . add 0.25x to both sides
-1.50 = -0.50x . . . . . . . . . . . . . the correct result from the addition (Step 2)

The correct result is ...
x = -1.50/-0.50 = 3 . . . . . Step 3
Answer:
-127.488°
Step-by-step explanation:
45" is 0.75 of 1', so -128° 30' 45" = -128° 30.75'
Next: 30.75' is 30.75/60 of 1°, and or -128° plus 0.5125 of 1°.
The final answer is found by adding 0.5125° to -128°:
-128.0000°
+ 0.5125°
--------------------
-127.4875
To the nearest thousandths of a degree, that would be -127.488°
