Match the pairs of equivalent expressions.

these are the numbers $\fs3 \left ( \text{-}14\:+\:\frac{3}{2}b\right )\:-\:\left ( 1\:+\:\frac{8}{2}b \right )$
$\fs3 4b\:+\:\frac{13}{2}$
$\fs3 \left ( 5\:+\:2b \right )\:+\:\left ( 2b\:+\:\frac{3}{2} \right )$
$\fs3 8b - 15$
$\fs3 \left ( \frac{7}{2}b\:-\:3\right )\:-\:\left ( 8\:+\:6b \right )$
$\fs3 \text{-}\frac{5}{2}b\:-\:11$
$\fs3 (\text{-}10 + b) + (7b - 5)$
$\fs3 \text{-}15\:-\:\frac{5}{2}b$

Hi Galvin, subtract the second binomial from the first binomial gives -15 - 5/2*b

Only the last expression matches this.

The other four expressions do not match
