Uża l-propjetà distributtiva biex timmultiplika 3 b'y-6.

$$3y-18+4\left(-4-y\right)=-12\left(y-3\right)+4$$

Uża l-propjetà distributtiva biex timmultiplika 4 b'-4-y.

$$3y-18-16-4y=-12\left(y-3\right)+4$$

Naqqas 16 minn -18 biex tikseb -34.

$$3y-34-4y=-12\left(y-3\right)+4$$

Ikkombina 3y u -4y biex tikseb -y.

$$-y-34=-12\left(y-3\right)+4$$

Uża l-propjetà distributtiva biex timmultiplika -12 b'y-3.

$$-y-34=-12y+36+4$$

Żid 36 u 4 biex tikseb 40.

$$-y-34=-12y+40$$

Żid 12y maż-żewġ naħat.

$$-y-34+12y=40$$

Ikkombina -y u 12y biex tikseb 11y.

$$11y-34=40$$

Żid 34 maż-żewġ naħat.

$$11y=40+34$$

Żid 40 u 34 biex tikseb 74.

$$11y=74$$

Iddividi ż-żewġ naħat b'11.

$$y=\frac{74}{11}$$
