Whakaoti i te (5t_{6}+3+a+b-a)+20=305

$$( 5 t _ { 6 } + 3 + a + b - a ) + 20 = 305$$

Whakaoti mō b

$$b=282-5t_{6}$$

Ngā Upane Otinga

Pahekotia te a me -a, ka 0.

$$5t_{6}+3+b+20=305$$

Tāpirihia te 3 ki te 20, ka 23.

$$5t_{6}+23+b=305$$

Tangohia te 5t_{6} mai i ngā taha e rua.

$$23+b=305-5t_{6}$$

Tangohia te 23 mai i ngā taha e rua.

$$b=305-5t_{6}-23$$

Tangohia te 23 i te 305, ka 282.

$$b=282-5t_{6}$$

Whakaoti mō a (complex solution)

$$a\in \mathrm{C}$$

$$t_{6}=\frac{282-b}{5}$$

Whakaoti mō a

$$a\in \mathrm{R}$$

$$t_{6}=\frac{282-b}{5}$$
