1, Assuming both arguments are positive
x - 5 = -2x + 6
2x - 5 = 6
2x = 11
x = 5.5
2. Assuming both arguments are negative
-(x - 5) = -(-2x + 6)
x - 5 = -2x + 6
x = 5.5
3. Assuming the first positive, second negative
x - 5 = -(-2x + 6)
x - 5 = 2x - 6
-5 = x - 6
1 = x
4. Assuming the first negative, second positive
-(x - 5) = -2x + 6
-x + 5 = -2x + 6
x = 1
