Solvi għal x, y

$$y = \frac{936}{125} = 7\frac{61}{125} = 7.488$$

Passi tas-Soluzzjonijiet

Ikkunsidra l-ewwel ekwazzjoni. Iddividi ż-żewġ naħat b'5.

$$x=\frac{6}{5}$$

Ikkunsidra t-tieni ekwazzjoni. Inserixxi l-valuri magħrufa tal-varjabbli fl-ekwazzjoni.

$$y=\left(\frac{6}{5}\right)^{3}+4\times \left(\frac{6}{5}\right)^{2}$$

Ikkalkula \frac{6}{5} bil-power ta' 3 u tikseb \frac{216}{125}.

$$y=\frac{216}{125}+4\times \left(\frac{6}{5}\right)^{2}$$

Ikkalkula \frac{6}{5} bil-power ta' 2 u tikseb \frac{36}{25}.

$$y=\frac{216}{125}+4\times \frac{36}{25}$$

Immultiplika 4 u \frac{36}{25} biex tikseb \frac{144}{25}.

$$y=\frac{216}{125}+\frac{144}{25}$$

Żid \frac{216}{125} u \frac{144}{25} biex tikseb \frac{936}{125}.

$$y=\frac{936}{125}$$

Is-sistema issa solvuta.

$$x=\frac{6}{5} y=\frac{936}{125}$$
