Whakaoti i te 1(v-7)+039y=003y-020

$$1 ( v - 7 ) + 039 y = 003 y - 020$$

Whakaoti mō v

$$v=7$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 1 ki te v-7.

$$v-7+0\times 39y=0\times 0\times 3y-0\times 20$$

Whakareatia te 0 ki te 39, ka 0.

$$v-7+0y=0\times 0\times 3y-0\times 20$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$v-7+0=0\times 0\times 3y-0\times 20$$

Tāpirihia te -7 ki te 0, ka -7.

$$v-7=0\times 0\times 3y-0\times 20$$

Whakareatia te 0 ki te 0, ka 0.

$$v-7=0\times 3y-0\times 20$$

Whakareatia te 0 ki te 3, ka 0.

$$v-7=0y-0\times 20$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$v-7=0-0\times 20$$

Whakareatia te 0 ki te 20, ka 0.

$$v-7=0-0$$

Mā te tango i te 0 i a ia ake anō ka toe ko te 0.

$$v-7=0$$

Me tāpiri te 7 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$v=7$$

Whakaoti mō y (complex solution)

$$y\in \mathrm{C}$$

$$v=7$$

Whakaoti mō y

$$y\in \mathrm{R}$$

$$v=7$$
