Whakaoti i te 8left(x-1right)=8-4left(2x-3right)

$$8 \left( x-1 \right) = 8-4 \left( 2x-3 \right)$$

Whakaoti mō x

$$x = \frac{7}{4} = 1\frac{3}{4} = 1.75$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te x-1.

$$8x-8=8-4\left(2x-3\right)$$

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

$$8x-8=8-8x+12$$

Tāpirihia te 8 ki te 12, ka 20.

$$8x-8=20-8x$$

Me tāpiri te 8x ki ngā taha e rua.

$$8x-8+8x=20$$

Pahekotia te 8x me 8x, ka 16x.

$$16x-8=20$$

Me tāpiri te 8 ki ngā taha e rua.

$$16x=20+8$$

Tāpirihia te 20 ki te 8, ka 28.

$$16x=28$$

Whakawehea ngā taha e rua ki te 16.

$$x=\frac{28}{16}$$

Whakahekea te hautanga \frac{28}{16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$x=\frac{7}{4}$$
