Answer:

  4x -3

Step-by-step explanation:

The distributive property applies.

  3x +4(x -6) -3(x -7)

  = 3x +4x +4(-6) -3x -3(-7) . . . . use the distributive property

  = 3x +4x -24 -3x +21 . . . . . . . . simplify

  = x(3 +4 -3) +(-24 +21) . . . . . . . group like terms, use the distributive property again

  = 4x -3 . . . . simplify
