6(2x + 3) - 7(3x - 4) = 12x + 18 - 21x + 28 = -9x + 46
4(3x + 7) - 6(2x + 5) = 12x + 28 - 12x - 30 = -2
-16(x - 4) + 2.3 = -16x + 64 + 2.3 = -16x + 66.3
3(2x - 7) - 8 = 6x - 21 - 8 = 6x - 29

Therefore, the equation becomes:
-9x + 46 = 6x - 29 + 5x + 66.3

Combining like terms:
-9x - 6x - 5x = -20x
46 = -29 + 66.3
46 = 37.3

There is no solution to this equation.
