Kindly check below.
1) Examining the expressions inside the tiles, we can tell that:
[tex]\begin{gathered} (-14+\frac{3}{2}b)-(1+\frac{8}{2}b)=-\frac{5}{2}b-15 \\ 4b+\frac{13}{2} \\ (5+2b)+(2b+\frac{3}{2})=4b+\frac{13}{2} \\ 8b-15 \\ (\frac{7}{2}b-3)-(8+6b)=\frac{7}{2}b-3-8-6b\rightarrow-11-\frac{5}{2}b \\ -\frac{5}{2}b-11 \\ (-10+b)+(7b-5)=8b-15 \\ -15-\frac{5}{2}b \end{gathered}[/tex]
2) Based on this we can tell the following relationship of equivalence:
