Issolvi 30x+80(06-12-x)=(12-x)*90

$$30x+80(06-12-x)=(12-x) \times 90$$

Solvi għal x

$$x=51$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Immultiplika 0 u 6 biex tikseb 0.

$$30x+80\left(0-12-x\right)=\left(12-x\right)\times 90$$

Naqqas 12 minn 0 biex tikseb -12.

$$30x+80\left(-12-x\right)=\left(12-x\right)\times 90$$

Uża l-propjetà distributtiva biex timmultiplika 80 b'-12-x.

$$30x-960-80x=\left(12-x\right)\times 90$$

Ikkombina 30x u -80x biex tikseb -50x.

$$-50x-960=\left(12-x\right)\times 90$$

Uża l-propjetà distributtiva biex timmultiplika 12-x b'90.

$$-50x-960=1080-90x$$

Żid 90x maż-żewġ naħat.

$$-50x-960+90x=1080$$

Ikkombina -50x u 90x biex tikseb 40x.

$$40x-960=1080$$

Żid 960 maż-żewġ naħat.

$$40x=1080+960$$

Żid 1080 u 960 biex tikseb 2040.

$$40x=2040$$

Iddividi ż-żewġ naħat b'40.

$$x=\frac{2040}{40}$$

Iddividi 2040 b'40 biex tikseb51.

$$x=51$$
