$$x + x + 6 + x + 6 + 4 = 28$$

Whakaoti mō x

$$x=4$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Pahekotia te x me x, ka 2x.

$$2x+6+x+6+4=28$$

Pahekotia te 2x me x, ka 3x.

$$3x+6+6+4=28$$

Tāpirihia te 6 ki te 6, ka 12.

$$3x+12+4=28$$

Tāpirihia te 12 ki te 4, ka 16.

$$3x+16=28$$

Tangohia te 16 mai i ngā taha e rua.

$$3x=28-16$$

Tangohia te 16 i te 28, ka 12.

$$3x=12$$

Whakawehea ngā taha e rua ki te 3.

$$x=\frac{12}{3}$$

Whakawehea te 12 ki te 3, kia riro ko 4.

$$x=4$$
