Answer:

  m = 3; b = -12

Step-by-step explanation:

In order to answer the question definitively, we must assume you intend for the equation to be an identity.

  6(2x -5) -(mx +2) = 9x +b

  12x -10 -mx -2 = 9x +b

Equating x terms:

  12x -mx = 9x

  12 -m = 9 . . . . . . divide by x; next, add m-9

  12 -9 = m = 3

Equating constant terms:

  -10 -2 = b

  -12 = b
