Whakaoti i te x+-25*3-45-1/2=-41/5

$$x+-25 \cdot 3-45- \frac{ 1 }{ 2 } = -4 \frac{ 1 }{ 5 }$$

Whakaoti mō x

$$x = \frac{1163}{10} = 116\frac{3}{10} = 116.3$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 10, arā, te tauraro pātahi he tino iti rawa te kitea o 2,5.

$$10x-250\times 3-450-5=-2\left(4\times 5+1\right)$$

Whakareatia te -250 ki te 3, ka -750.

$$10x-750-450-5=-2\left(4\times 5+1\right)$$

Tangohia te 450 i te -750, ka -1200.

$$10x-1200-5=-2\left(4\times 5+1\right)$$

Tangohia te 5 i te -1200, ka -1205.

$$10x-1205=-2\left(4\times 5+1\right)$$

Whakareatia te 4 ki te 5, ka 20.

$$10x-1205=-2\left(20+1\right)$$

Tāpirihia te 20 ki te 1, ka 21.

$$10x-1205=-2\times 21$$

Whakareatia te -2 ki te 21, ka -42.

$$10x-1205=-42$$

Me tāpiri te 1205 ki ngā taha e rua.

$$10x=-42+1205$$

Tāpirihia te -42 ki te 1205, ka 1163.

$$10x=1163$$

Whakawehea ngā taha e rua ki te 10.

$$x=\frac{1163}{10}$$
