Passi tas-Soluzzjonijiet

Ikkunsidra l-ewwel ekwazzjoni. Iddividi ż-żewġ naħat b'9.

$$\frac{x+2\times 7}{4}=\frac{25}{9}$$

Immultiplika ż-żewġ naħat b'4.

$$x+2\times 7=\frac{25}{9}\times 4$$

Immultiplika 2 u 7 biex tikseb 14.

$$x+14=\frac{25}{9}\times 4$$

Immultiplika \frac{25}{9} u 4 biex tikseb \frac{100}{9}.

$$x+14=\frac{100}{9}$$

Naqqas 14 miż-żewġ naħat.

$$x=\frac{100}{9}-14$$

Naqqas 14 minn \frac{100}{9} biex tikseb -\frac{26}{9}.

$$x=-\frac{26}{9}$$

Is-sistema issa solvuta.

$$x=-\frac{26}{9} y=3 z=3 a=3 b=3$$
