Issolvi 0.12(y-8)+0.16y=0.18y-0.03(40)

$$0.12 ( y - 8 ) + 0.16 y = 0.18 y - 0.03 ( 40 )$$

Solvi għal y

$$y=-2.4$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Uża l-propjetà distributtiva biex timmultiplika 0.12 b'y-8.

$$0.12y-0.96+0.16y=0.18y-0.03\times 40$$

Ikkombina 0.12y u 0.16y biex tikseb 0.28y.

$$0.28y-0.96=0.18y-0.03\times 40$$

Immultiplika 0.03 u 40 biex tikseb 1.2.

$$0.28y-0.96=0.18y-1.2$$

Naqqas 0.18y miż-żewġ naħat.

$$0.28y-0.96-0.18y=-1.2$$

Ikkombina 0.28y u -0.18y biex tikseb 0.1y.

$$0.1y-0.96=-1.2$$

Żid 0.96 maż-żewġ naħat.

$$0.1y=-1.2+0.96$$

Żid -1.2 u 0.96 biex tikseb -0.24.

$$0.1y=-0.24$$

Iddividi ż-żewġ naħat b'0.1.

$$y=\frac{-0.24}{0.1}$$

Espandi \frac{-0.24}{0.1} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'100.

$$y=\frac{-24}{10}$$

Naqqas il-frazzjoni \frac{-24}{10} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 2.

$$y=-\frac{12}{5}$$
