\frac{\left(7-9\right)\left(5x+10\right)}{5\left(2^{5}-7\right)}
Iddividi \frac{7-9}{5} b'\frac{2^{5}-7}{5x+10} billi timmultiplika \frac{7-9}{5} bir-reċiproku ta' \frac{2^{5}-7}{5x+10}.
\frac{-2\left(5x+10\right)}{5\left(2^{5}-7\right)}
Naqqas 9 minn 7 biex tikseb -2.
\frac{-2\left(5x+10\right)}{5\left(32-7\right)}
Ikkalkula 2 bil-power ta' 5 u tikseb 32.
\frac{-2\left(5x+10\right)}{5\times 25}
Naqqas 7 minn 32 biex tikseb 25.
\frac{-2\left(5x+10\right)}{125}
Immultiplika 5 u 25 biex tikseb 125.
\frac{-10x-20}{125}
Uża l-propjetà distributtiva biex timmultiplika -2 b'5x+10.
