Whakaoti i te y*6+42-y*8=276

$$y \times 6+42-y \times 8=276$$

Whakaoti mō y

$$y=-117$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Pahekotia te y\times 6 me -y\times 8, ka -2y.

$$-2y+42=276$$

Tangohia te 42 mai i ngā taha e rua.

$$-2y=276-42$$

Tangohia te 42 i te 276, ka 234.

$$-2y=234$$

Whakawehea ngā taha e rua ki te -2.

$$y=\frac{234}{-2}$$

Whakawehea te 234 ki te -2, kia riro ko -117.

$$y=-117$$
