Whakaoti i te x=4/3-2/3*13/5

$$x = \frac { 4 } { 3 } - \frac { 2 } { 3 } \cdot \frac { 13 } { 5 }$$

Whakaoti mō x

$$x=-\frac{2}{5}=-0.4$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea te \frac{2}{3} ki te \frac{13}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$x=\frac{4}{3}-\frac{2\times 13}{3\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{2\times 13}{3\times 5}.

$$x=\frac{4}{3}-\frac{26}{15}$$

Ko te maha noa iti rawa atu o 3 me 15 ko 15. Me tahuri \frac{4}{3} me \frac{26}{15} ki te hautau me te tautūnga 15.

$$x=\frac{20}{15}-\frac{26}{15}$$

Tā te mea he rite te tauraro o \frac{20}{15} me \frac{26}{15}, me tango rāua mā te tango i ō raua taurunga.

$$x=\frac{20-26}{15}$$

Tangohia te 26 i te 20, ka -6.

$$x=\frac{-6}{15}$$

Whakahekea te hautanga \frac{-6}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

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

Tautapa x

$$x≔-\frac{2}{5}$$
