Issolvi -3y+6(5y+6)=1-8(7-y)

$$- 3 y + 6 ( 5 y + 6 ) = 1 - 8 ( 7 - y )$$

Solvi għal y

$$y = -\frac{91}{19} = -4\frac{15}{19} \approx -4.789473684$$

Uża l-propjetà distributtiva biex timmultiplika 6 b'5y+6.

$$-3y+30y+36=1-8\left(7-y\right)$$

Ikkombina -3y u 30y biex tikseb 27y.

$$27y+36=1-8\left(7-y\right)$$

Uża l-propjetà distributtiva biex timmultiplika -8 b'7-y.

$$27y+36=1-56+8y$$

Naqqas 56 minn 1 biex tikseb -55.

$$27y+36=-55+8y$$

Naqqas 8y miż-żewġ naħat.

$$27y+36-8y=-55$$

Ikkombina 27y u -8y biex tikseb 19y.

$$19y+36=-55$$

Naqqas 36 miż-żewġ naħat.

$$19y=-55-36$$

Naqqas 36 minn -55 biex tikseb -91.

$$19y=-91$$

Iddividi ż-żewġ naħat b'19.

$$y=\frac{-91}{19}$$

Frazzjoni \frac{-91}{19} tista' tinkiteb mill-ġdid bħala -\frac{91}{19} bl-estrazzjoni tas-sinjal negattiv.

$$y=-\frac{91}{19}$$
