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

$$2x-2+3=5x-29$$

Tāpirihia te -2 ki te 3, ka 1.

$$2x+1=5x-29$$

Tangohia te 5x mai i ngā taha e rua.

$$2x+1-5x=-29$$

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

$$-3x+1=-29$$

Tangohia te 1 mai i ngā taha e rua.

$$-3x=-29-1$$

Tangohia te 1 i te -29, ka -30.

$$-3x=-30$$

Whakawehea ngā taha e rua ki te -3.

$$x=\frac{-30}{-3}$$

Whakawehea te -30 ki te -3, kia riro ko 10.

$$x=10$$

Whakaarohia te whārite tuarua. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$y=10+1\times 10-2$$

Whakareatia te 1 ki te 10, ka 10.

$$y=10+10-2$$

Tāpirihia te 10 ki te 10, ka 20.

$$y=20-2$$

Tangohia te 2 i te 20, ka 18.

$$y=18$$

Whakaarohia te whārite tuatoru. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$z=18$$

Whakaarohia te whārite tuawhā. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$a=18$$

Whakaarohia te whārite tuarima. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$b=18$$

Whakaarohia te whārite (6). Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$c=18$$

Kua oti te pūnaha te whakatau.

$$x=10 y=18 z=18 a=18 b=18 c=18$$
