\frac{11z\times 6}{-15\left(7z+21\right)}
Iddividi \frac{11z}{-15} b'\frac{7z+21}{6} billi timmultiplika \frac{11z}{-15} bir-reċiproku ta' \frac{7z+21}{6}.
\frac{2\times 11z}{-5\left(7z+21\right)}
Annulla 3 fin-numeratur u d-denominatur.
\frac{22z}{-5\left(7z+21\right)}
Immultiplika 2 u 11 biex tikseb 22.
\frac{22z}{-35z-105}
Uża l-propjetà distributtiva biex timmultiplika -5 b'7z+21.
