If you mean: -5x+14x = 48+14 then 9x = 62 and the value of x equals 62/9 = 6.'8' recurring '8'
12 plus 9 equals 21.
2 plus 3 equals 5 7 plus 2 equals 9 6 plus 9 equals 15 8 plus 4 equals 12 9 plus 7 equals 16 Am I missing something here? Probably. You say 2+3=5, but the question clearly states 2+3=10. Why would it say that? Suppose you had only one hand. You count 1,2,3,4,5,10,11,12. That last doesn't mean "twelve" as we know it, Jim. It means one hand (5), plus 2 spare ones. We could say: if 2+3=10, 5+2=12.
144 9+7 = 16 and 9*16 = 144
The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.

9 plus 87 equals 96.
12 plus 9 equals 21.
No! It equals 15, but 9-6=3.
96
2 plus 3 equals 5 7 plus 2 equals 9 6 plus 9 equals 15 8 plus 4 equals 12 9 plus 7 equals 16 Am I missing something here? Probably. You say 2+3=5, but the question clearly states 2+3=10.

9+9+9+9 = 36
If I am correct, 9 plus 7 equals 112.
144 9+7 = 16 and 9*16 = 144
The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.
9+9+9+9+9+9+9=63
