Whakareatia te 256 ki te 150, ka 38400. Whakareatia te 15 ki te 50, ka 750.

$$240x\times 362+38400+750+100=1400$$

Whakareatia te 240 ki te 362, ka 86880.

$$86880x+38400+750+100=1400$$

Tāpirihia te 38400 ki te 750, ka 39150.

$$86880x+39150+100=1400$$

Tāpirihia te 39150 ki te 100, ka 39250.

$$86880x+39250=1400$$

Tangohia te 39250 mai i ngā taha e rua.

$$86880x=1400-39250$$

Tangohia te 39250 i te 1400, ka -37850.

$$86880x=-37850$$

Whakawehea ngā taha e rua ki te 86880.

$$x=\frac{-37850}{86880}$$
