Whakaoti i te 995+(x-1)*-3=5+(x-1)2

$$995+(x-1) \times -3=5+(x-1)2$$

Whakaoti mō x

$$x=199$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te x-1 ki te -3.

$$995-3x+3=5+\left(x-1\right)\times 2$$

Tāpirihia te 995 ki te 3, ka 998.

$$998-3x=5+\left(x-1\right)\times 2$$

Whakamahia te āhuatanga tohatoha hei whakarea te x-1 ki te 2.

$$998-3x=5+2x-2$$

Tangohia te 2 i te 5, ka 3.

$$998-3x=3+2x$$

Tangohia te 2x mai i ngā taha e rua.

$$998-3x-2x=3$$

Pahekotia te -3x me -2x, ka -5x.

$$998-5x=3$$

Tangohia te 998 mai i ngā taha e rua.

$$-5x=3-998$$

Tangohia te 998 i te 3, ka -995.

$$-5x=-995$$

Whakawehea ngā taha e rua ki te -5.

$$x=\frac{-995}{-5}$$

Whakawehea te -995 ki te -5, kia riro ko 199.

$$x=199$$
