Issolvi 77-50/50-28=3-x/x+1

$$\frac { 77 - 50 } { 50 - 28 } = \frac { 3 - x } { x + 1 }$$

Solvi għal x

$$x=\frac{39}{49}\approx 0.795918367$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Il-varjabbli x ma jistax ikun ugwali għal -1 billi d-diviżjoni b'żero mhux iddefinit. Immultiplika ż-żewġ naħat tal-ekwazzjoni b'x+1.

$$\left(\frac{1}{22}x+\frac{1}{22}\right)\left(77-50\right)=3-x$$

Naqqas 50 minn 77 biex tikseb 27.

$$\left(\frac{1}{22}x+\frac{1}{22}\right)\times 27=3-x$$

Uża l-propjetà distributtiva biex timmultiplika \frac{1}{22}x+\frac{1}{22} b'27.

$$\frac{27}{22}x+\frac{27}{22}=3-x$$

Żid x maż-żewġ naħat.

$$\frac{27}{22}x+\frac{27}{22}+x=3$$

Ikkombina \frac{27}{22}x u x biex tikseb \frac{49}{22}x.

$$\frac{49}{22}x+\frac{27}{22}=3$$

Naqqas \frac{27}{22} miż-żewġ naħat.

$$\frac{49}{22}x=3-\frac{27}{22}$$

Naqqas \frac{27}{22} minn 3 biex tikseb \frac{39}{22}.

$$\frac{49}{22}x=\frac{39}{22}$$

Immultiplika ż-żewġ naħat b'\frac{22}{49}, ir-reċiproku ta' \frac{49}{22}.

$$x=\frac{39}{22}\times \frac{22}{49}$$

Immultiplika \frac{39}{22} u \frac{22}{49} biex tikseb \frac{39}{49}.

$$x=\frac{39}{49}$$
