Answer: A, C, F

Explanation:

Simplifying the equations by combining like terms,

$A. \text{ } 8b+11=8b-11 \longrightarrow 11=-11\\\\B. \text{ } 11b-19=11b-19 \longrightarrow 0=0\\\\C. \text{ } -7b+5=-7b+7 \longrightarrow -5=7\\\\D. \text{ } 12=4b \longrightarrow b=3\\\\E. \text{ } -14b=0 \longrightarrow b=0\\\\F. \text{ } 12b-8=12b-14 \longrightarrow -8=-14$

Since choices A, C, and F result in false statements, they have no solutions.
