Issolvi 1-x+1/9(x+18)+1/3(2x+3)=3

$$1 - x + 1 / 9 ( x + 18 ) + 1 / 3 ( 2 x + 3 ) = 3$$

Solvi għal x

$$x = \frac{9}{2} = 4\frac{1}{2} = 4.5$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Uża l-propjetà distributtiva biex timmultiplika \frac{1}{9} b'x+18.

$$1-x+\frac{1}{9}x+\frac{1}{9}\times 18+\frac{1}{3}\left(2x+3\right)=3$$

Immultiplika \frac{1}{9} u 18 biex tikseb \frac{18}{9}.

$$1-x+\frac{1}{9}x+\frac{18}{9}+\frac{1}{3}\left(2x+3\right)=3$$

Iddividi 18 b'9 biex tikseb2.

$$1-x+\frac{1}{9}x+2+\frac{1}{3}\left(2x+3\right)=3$$

Ikkombina -x u \frac{1}{9}x biex tikseb -\frac{8}{9}x.

$$1-\frac{8}{9}x+2+\frac{1}{3}\left(2x+3\right)=3$$

Żid 1 u 2 biex tikseb 3.

$$3-\frac{8}{9}x+\frac{1}{3}\left(2x+3\right)=3$$

Uża l-propjetà distributtiva biex timmultiplika \frac{1}{3} b'2x+3.

$$3-\frac{8}{9}x+\frac{1}{3}\times 2x+\frac{1}{3}\times 3=3$$

Immultiplika \frac{1}{3} u 2 biex tikseb \frac{2}{3}.

$$3-\frac{8}{9}x+\frac{2}{3}x+\frac{1}{3}\times 3=3$$

Annulla 3 u 3.

$$3-\frac{8}{9}x+\frac{2}{3}x+1=3$$

Ikkombina -\frac{8}{9}x u \frac{2}{3}x biex tikseb -\frac{2}{9}x.

$$3-\frac{2}{9}x+1=3$$

Żid 3 u 1 biex tikseb 4.

$$4-\frac{2}{9}x=3$$

Naqqas 4 miż-żewġ naħat.

$$-\frac{2}{9}x=3-4$$

Naqqas 4 minn 3 biex tikseb -1.

$$-\frac{2}{9}x=-1$$

Immultiplika ż-żewġ naħat b'-\frac{9}{2}, ir-reċiproku ta' -\frac{2}{9}.

$$x=-\left(-\frac{9}{2}\right)$$

Immultiplika -1 u -\frac{9}{2} biex tikseb \frac{9}{2}.

$$x=\frac{9}{2}$$
