Procedura per la soluzione di equazioni lineari

Moltiplica entrambi i lati dell'equazione per 434.

$$-663\times 10^{-34}\times 3\times 10^{9}=94612\times 10^{-18}x$$

Calcola 10 alla potenza di -34 e ottieni \frac{1}{10000000000000000000000000000000000}.

$$-663\times \frac{1}{10000000000000000000000000000000000}\times 3\times 10^{9}=94612\times 10^{-18}x$$

Moltiplica -663 e \frac{1}{10000000000000000000000000000000000} per ottenere -\frac{663}{10000000000000000000000000000000000}.

$$-\frac{663}{10000000000000000000000000000000000}\times 3\times 10^{9}=94612\times 10^{-18}x$$

Moltiplica -\frac{663}{10000000000000000000000000000000000} e 3 per ottenere -\frac{1989}{10000000000000000000000000000000000}.

$$-\frac{1989}{10000000000000000000000000000000000}\times 10^{9}=94612\times 10^{-18}x$$

Calcola 10 alla potenza di 9 e ottieni 1000000000.

$$-\frac{1989}{10000000000000000000000000000000000}\times 1000000000=94612\times 10^{-18}x$$

Moltiplica -\frac{1989}{10000000000000000000000000000000000} e 1000000000 per ottenere -\frac{1989}{10000000000000000000000000}.

$$-\frac{1989}{10000000000000000000000000}=94612\times 10^{-18}x$$

Calcola 10 alla potenza di -18 e ottieni \frac{1}{1000000000000000000}.

$$-\frac{1989}{10000000000000000000000000}=94612\times \frac{1}{1000000000000000000}x$$

Moltiplica 94612 e \frac{1}{1000000000000000000} per ottenere \frac{23653}{250000000000000000}.

$$-\frac{1989}{10000000000000000000000000}=\frac{23653}{250000000000000000}x$$

Scambia i lati in modo che i termini variabili si trovino sul lato sinistro.

$$\frac{23653}{250000000000000000}x=-\frac{1989}{10000000000000000000000000}$$

Moltiplica entrambi i lati per \frac{250000000000000000}{23653}, il reciproco di \frac{23653}{250000000000000000}.

$$x=-\frac{1989}{10000000000000000000000000}\times \frac{250000000000000000}{23653}$$

Moltiplica -\frac{1989}{10000000000000000000000000} e \frac{250000000000000000}{23653} per ottenere -\frac{1989}{946120000000}.

$$x=-\frac{1989}{946120000000}$$
