Whakaoti i te x=(frac{sqrt{2}}{2})(-3)-(frac{sqrt{2}}{2})(4)

$$x=( \frac{ \sqrt{ 2 } }{ 2 } )(-3)-( \frac{ \sqrt{ 2 } }{ 2 } )(4)$$

Whakaoti mō x

$$x = -\frac{7 \sqrt{2}}{2} \approx -4.949747468$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tuhia te \frac{\sqrt{2}}{2}\left(-3\right) hei hautanga kotahi.

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

Whakakorea atu te tauwehe pūnoa nui rawa 2 i roto i te 4 me te 2.

$$x=\frac{-\sqrt{2}\times 3}{2}-2\sqrt{2}$$

Whakareatia te -1 ki te 3, ka -3.

$$x=\frac{-3\sqrt{2}}{2}-2\sqrt{2}$$

Pahekotia te \frac{-3\sqrt{2}}{2} me -2\sqrt{2}, ka -\frac{7}{2}\sqrt{2}.

$$x=-\frac{7}{2}\sqrt{2}$$

Tautapa x

$$x≔-\frac{7\sqrt{2}}{2}$$
