Riješi +72=-+x*10^-19

$$+72=-+x \times { 10 }^{ -19 }$$

Izračunaj x

$$x=-720000000000000000000$$

Koraci rješavanja linearne jednadžbe

Izračunajte koliko je -19 na 10 da biste dobili \frac{1}{10000000000000000000}.

$$72=\left(-x\right)\times \frac{1}{10000000000000000000}$$

Zamijenite strane tako da svi izrazi s nepoznanicama budu s lijeve strane.

$$\left(-x\right)\times \frac{1}{10000000000000000000}=72$$

Pomnožite obje strane s 10000000000000000000, recipročnim izrazom od \frac{1}{10000000000000000000}.

$$-x=72\times 10000000000000000000$$

Pomnožite 72 i 10000000000000000000 da biste dobili 720000000000000000000.

$$-x=720000000000000000000$$

Pomnožite obje strane s -1.

$$x=-720000000000000000000$$
