96
9 plus 87 equals 96.
12b - 9 + 2b - b = -87 13b - 9 = -87 13b = -87 +9 13b = -78 b = -6
348
Answer is 43.4444
44 - 9 + 6 + 5 + 4 + 32 + 5 = 87
87 + 15 + 48 = 150
765
87+42+78 = 207
1 + 55 + 345 + 87 + 98 = 586
87 / 9 = 9.6 recurring (that is, 9.666... or 9 and two thirds). Therefore, 9 does not go evenly into 87.
87+7= 94
99 + 87 = 186
