Answer:
1 is allowed on the elevator.
2 is allowed on the elevator.
3 is allowed on the elevator.
4 is not allowed on the elevator.
5 is allowed on the elevator.
Step-by-step explanation:
If the maximum weight capacity of the elevator is 750 pounds, then that means every weight that is 750 pounds or less is allowed on the elevator.
1 is allowed because 700lbs is lower than 750lbs, therefore it is safe.
2 is allowed for the same reason, 620lbs is lower than 750lbs.
etc, etc.
So that's all you need to look for :)

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