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
