Whakaoti i te 4*(3x-8)+7=19-4*(3x-1)

$$4 \cdot ( 3 x - 8 ) + 7 = 19 - 4 \cdot ( 3 x - 1 )$$

Whakaoti mō x

$$x=2$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 3x-8.

$$12x-32+7=19-4\left(3x-1\right)$$

Tāpirihia te -32 ki te 7, ka -25.

$$12x-25=19-4\left(3x-1\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te 3x-1.

$$12x-25=19-12x+4$$

Tāpirihia te 19 ki te 4, ka 23.

$$12x-25=23-12x$$

Me tāpiri te 12x ki ngā taha e rua.

$$12x-25+12x=23$$

Pahekotia te 12x me 12x, ka 24x.

$$24x-25=23$$

Me tāpiri te 25 ki ngā taha e rua.

$$24x=23+25$$

Tāpirihia te 23 ki te 25, ka 48.

$$24x=48$$

Whakawehea ngā taha e rua ki te 24.

$$x=\frac{48}{24}$$

Whakawehea te 48 ki te 24, kia riro ko 2.

$$x=2$$
