Issolvi 5(x+3)+12x=4-7(2-x)

$$5(x+3)+12x=4-7(2-x)$$

Solvi għal x

$$x = -\frac{5}{2} = -2\frac{1}{2} = -2.5$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Uża l-propjetà distributtiva biex timmultiplika 5 b'x+3.

$$5x+15+12x=4-7\left(2-x\right)$$

Ikkombina 5x u 12x biex tikseb 17x.

$$17x+15=4-7\left(2-x\right)$$

Uża l-propjetà distributtiva biex timmultiplika -7 b'2-x.

$$17x+15=4-14+7x$$

Naqqas 14 minn 4 biex tikseb -10.

$$17x+15=-10+7x$$

Naqqas 7x miż-żewġ naħat.

$$17x+15-7x=-10$$

Ikkombina 17x u -7x biex tikseb 10x.

$$10x+15=-10$$

Naqqas 15 miż-żewġ naħat.

$$10x=-10-15$$

Naqqas 15 minn -10 biex tikseb -25.

$$10x=-25$$

Iddividi ż-żewġ naħat b'10.

$$x=\frac{-25}{10}$$

Naqqas il-frazzjoni \frac{-25}{10} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 5.

$$x=-\frac{5}{2}$$
