17 + 25 + 23 = 65
-17/23 and the intercept is 25/23
23+17 is 40.
23 + 3 + 17 + 7 = 50
25
-17 plus 40 is 23 so put them all together it will be -17+40= 23
17 + 25 + 15 = 57
23 - 45 + 17 = -5
25 + 17 = 42
17 + 11 + 25 - 12 = 41
17 + 11 + (25-12) = 17 + 11 + 25 - 12 = 41.
-25
Are you for real?! Just substitute it. 17 plus 23 is 40.
