Issolvi 800*0.1(t-130)+400(t-10)=0

$$800 \times 0.1 ( t - 130 ) + 400 ( t - 10 ) = 0$$

Solvi għal t

$$t=30$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Immultiplika 800 u 0.1 biex tikseb 80.

$$80\left(t-130\right)+400\left(t-10\right)=0$$

Uża l-propjetà distributtiva biex timmultiplika 80 b't-130.

$$80t-10400+400\left(t-10\right)=0$$

Uża l-propjetà distributtiva biex timmultiplika 400 b't-10.

$$80t-10400+400t-4000=0$$

Ikkombina 80t u 400t biex tikseb 480t.

$$480t-10400-4000=0$$

Naqqas 4000 minn -10400 biex tikseb -14400.

$$480t-14400=0$$

Żid 14400 maż-żewġ naħat. Xi ħaġa plus żero jirriżulta f'dan in-numru stess.

$$480t=14400$$

Iddividi ż-żewġ naħat b'480.

$$t=\frac{14400}{480}$$

Iddividi 14400 b'480 biex tikseb30.

$$t=30$$
