Issolvi 0.12(y-2)+0.10y=0.18y-0.05(10)

$$0.12 ( y - 2 ) + 0.10 y = 0.18 y - 0.05 ( 10 )$$

Solvi għal y

$$y=-6.5$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Uża l-propjetà distributtiva biex timmultiplika 0.12 b'y-2.

$$0.12y-0.24+0.1y=0.18y-0.05\times 10$$

Ikkombina 0.12y u 0.1y biex tikseb 0.22y.

$$0.22y-0.24=0.18y-0.05\times 10$$

Immultiplika 0.05 u 10 biex tikseb 0.5.

$$0.22y-0.24=0.18y-0.5$$

Naqqas 0.18y miż-żewġ naħat.

$$0.22y-0.24-0.18y=-0.5$$

Ikkombina 0.22y u -0.18y biex tikseb 0.04y.

$$0.04y-0.24=-0.5$$

Żid 0.24 maż-żewġ naħat.

$$0.04y=-0.5+0.24$$

Żid -0.5 u 0.24 biex tikseb -0.26.

$$0.04y=-0.26$$

Iddividi ż-żewġ naħat b'0.04.

$$y=\frac{-0.26}{0.04}$$

Espandi \frac{-0.26}{0.04} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'100.

$$y=\frac{-26}{4}$$

Naqqas il-frazzjoni \frac{-26}{4} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 2.

$$y=-\frac{13}{2}$$
