-17 = x - 15
0 = x - 15 + 17
-x = 2
x = 2/(-1)
x = -2
0 = x - 15 + 17
-x = 2
x = 2/(-1)
x = -2

Add 15 to both sides to get x = -2

x = -2

I think it's -2... because +2 -15 = -13
參考: High school algebra like... 12 years ago! lol

- 17 = x - 15
+15 = +15
-2 = X
To confirm,
-17 = (-2) - 15 (does one side of the equation equal the other side?)
YES!
+15 = +15
-2 = X
To confirm,
-17 = (-2) - 15 (does one side of the equation equal the other side?)
