Issolvi 30=R*[1+39310^-3(0-20)]

$$30 = R \cdot [ 1 + 393 10 ^ { - 3 } ( 0 - 20 ) ]$$

Solvi għal R

$$R = -\frac{1500}{343} = -4\frac{128}{343} \approx -4.373177843$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Ikkalkula 10 bil-power ta' -3 u tikseb \frac{1}{1000}.

$$30=R\left(1+393\times \frac{1}{1000}\left(0-20\right)\right)$$

Immultiplika 393 u \frac{1}{1000} biex tikseb \frac{393}{1000}.

$$30=R\left(1+\frac{393}{1000}\left(0-20\right)\right)$$

Naqqas 20 minn 0 biex tikseb -20.

$$30=R\left(1+\frac{393}{1000}\left(-20\right)\right)$$

Immultiplika \frac{393}{1000} u -20 biex tikseb -\frac{393}{50}.

$$30=R\left(1-\frac{393}{50}\right)$$

Naqqas \frac{393}{50} minn 1 biex tikseb -\frac{343}{50}.

$$30=R\left(-\frac{343}{50}\right)$$

Ibdel in-naħat sabiex it-termini varjabbli kollha jkunu fuq in-naħa tax-xellug.

$$R\left(-\frac{343}{50}\right)=30$$

Immultiplika ż-żewġ naħat b'-\frac{50}{343}, ir-reċiproku ta' -\frac{343}{50}.

$$R=30\left(-\frac{50}{343}\right)$$

Immultiplika 30 u -\frac{50}{343} biex tikseb -\frac{1500}{343}.

$$R=-\frac{1500}{343}$$
