Whakaoti i te (x+90)*895=100x+8000

$$(x+90) \times 895=100x+8000$$

Whakaoti mō x

$$x = -\frac{14510}{159} = -91\frac{41}{159} \approx -91.257861635$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te x+90 ki te 895.

$$895x+80550=100x+8000$$

Tangohia te 100x mai i ngā taha e rua.

$$895x+80550-100x=8000$$

Pahekotia te 895x me -100x, ka 795x.

$$795x+80550=8000$$

Tangohia te 80550 mai i ngā taha e rua.

$$795x=8000-80550$$

Tangohia te 80550 i te 8000, ka -72550.

$$795x=-72550$$

Whakawehea ngā taha e rua ki te 795.

$$x=\frac{-72550}{795}$$

Whakahekea te hautanga \frac{-72550}{795} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$x=-\frac{14510}{159}$$
