Issolvi 2(y-1)+3(y-1)=4-2y

$$2 ( y - 1 ) + 3 ( y - 1 ) = 4 - 2 y$$

Solvi għal y

$$y = \frac{9}{7} = 1\frac{2}{7} \approx 1.285714286$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Uża l-propjetà distributtiva biex timmultiplika 2 b'y-1.

$$2y-2+3\left(y-1\right)=4-2y$$

Uża l-propjetà distributtiva biex timmultiplika 3 b'y-1.

$$2y-2+3y-3=4-2y$$

Ikkombina 2y u 3y biex tikseb 5y.

$$5y-2-3=4-2y$$

Naqqas 3 minn -2 biex tikseb -5.

$$5y-5=4-2y$$

Żid 2y maż-żewġ naħat.

$$5y-5+2y=4$$

Ikkombina 5y u 2y biex tikseb 7y.

$$7y-5=4$$

Żid 5 maż-żewġ naħat.

$$7y=4+5$$

Żid 4 u 5 biex tikseb 9.

$$7y=9$$

Iddividi ż-żewġ naħat b'7.

$$y=\frac{9}{7}$$
