Whakaoti i te 9(2x-1)+2(3x+4)=20x+3

$$9 ( 2 x - 1 ) + 2 ( 3 x + 4 ) = 20 x + 3$$

Whakaoti mō x

$$x=1$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te 2x-1.

$$18x-9+2\left(3x+4\right)=20x+3$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 3x+4.

$$18x-9+6x+8=20x+3$$

Pahekotia te 18x me 6x, ka 24x.

$$24x-9+8=20x+3$$

Tāpirihia te -9 ki te 8, ka -1.

$$24x-1=20x+3$$

Tangohia te 20x mai i ngā taha e rua.

$$24x-1-20x=3$$

Pahekotia te 24x me -20x, ka 4x.

$$4x-1=3$$

Me tāpiri te 1 ki ngā taha e rua.

$$4x=3+1$$

Tāpirihia te 3 ki te 1, ka 4.

$$4x=4$$

Whakawehea ngā taha e rua ki te 4.

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

Whakawehea te 4 ki te 4, kia riro ko 1.

$$x=1$$
