Whakaoti i te 2x-6/3-1=4-18-3x/4=

$$\frac { 2 x - 6 } { 3 } - 1 = 4 - \frac { 18 - 3 x } { 4 } =$$

Whakaoti mō x

$$x=-30$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 3,4.

$$4\left(2x-6\right)-12=48-3\left(18-3x\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 2x-6.

$$8x-24-12=48-3\left(18-3x\right)$$

Tangohia te 12 i te -24, ka -36.

$$8x-36=48-3\left(18-3x\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te 18-3x.

$$8x-36=48-54+9x$$

Tangohia te 54 i te 48, ka -6.

$$8x-36=-6+9x$$

Tangohia te 9x mai i ngā taha e rua.

$$8x-36-9x=-6$$

Pahekotia te 8x me -9x, ka -x.

$$-x-36=-6$$

Me tāpiri te 36 ki ngā taha e rua.

$$-x=-6+36$$

Tāpirihia te -6 ki te 36, ka 30.

$$-x=30$$

Me whakarea ngā taha e rua ki te -1.

$$x=-30$$
