Whakaoti i te 12(x+4)=8(x+8)-4

$$12 ( x + 4 ) = 8 ( x + 8 ) - 4$$

Whakaoti mō x

$$x=3$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 12 ki te x+4.

$$12x+48=8\left(x+8\right)-4$$

Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te x+8.

$$12x+48=8x+64-4$$

Tangohia te 4 i te 64, ka 60.

$$12x+48=8x+60$$

Tangohia te 8x mai i ngā taha e rua.

$$12x+48-8x=60$$

Pahekotia te 12x me -8x, ka 4x.

$$4x+48=60$$

Tangohia te 48 mai i ngā taha e rua.

$$4x=60-48$$

Tangohia te 48 i te 60, ka 12.

$$4x=12$$

Whakawehea ngā taha e rua ki te 4.

$$x=\frac{12}{4}$$

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

$$x=3$$
