15
x = 13
4 multiplyed by a number (Variable) plus 5 multiplyed by a number (V) equals 15 4v + 5v = 15 15/5 = v 15/4 = impossibility >_< Sorry :~) v = ImPoSiBiLiTy
x+15=16x=16-15x=1
If: 4x = x+15 Then: x = 5
2+14=16
Well there are quite a few numbers that added together will equal negative 15: here are just a few examples: negative 1 plus negative 14 equals negative 15 (-1 + -14 = -15) negative 2 plus negative 13 equals negative 15 (-2 + -13 = -15) negative 3 plus negative 12 equals negative 15 (-3 + -12 = -15) negative 4 plus negative 11 equals negative 15 (-4 + -11 = -15) negative 5 plus negative 10 equals negative 15 (-5 + -10 = -15) negative 6 plus negative 9 equals negative 15 (-6 + -9 = -15) negative 7 plus negative 8 equals negative 15 (-7 + -8 = -15) negative 30 plus positive 15 equals negative 15 (-30 + 15 = -15) negative 29 plus positive 14 equals negative 15 (-29 + 14 = -15) negative 28 plus positive 13 equals negative 15 (-28 + 13 = -15) and on an on it goes.
-14
-15 + 4 = -11
If: y+15 = 11 Then: y = -4
If: y+15 = 11 Then: y = -4
90 minus 75 =15 therefore 15 + 75 = 90
14 plus 15 equals 29.
