Whakaoti i te 4(2x+1)+7=7(4x-3)

$$4 ( 2 x + 1 ) + 7 = 7 ( 4 x - 3 )$$

Whakaoti mō x

$$x = \frac{8}{5} = 1\frac{3}{5} = 1.6$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 2x+1.

$$8x+4+7=7\left(4x-3\right)$$

Tāpirihia te 4 ki te 7, ka 11.

$$8x+11=7\left(4x-3\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te 4x-3.

$$8x+11=28x-21$$

Tangohia te 28x mai i ngā taha e rua.

$$8x+11-28x=-21$$

Pahekotia te 8x me -28x, ka -20x.

$$-20x+11=-21$$

Tangohia te 11 mai i ngā taha e rua.

$$-20x=-21-11$$

Tangohia te 11 i te -21, ka -32.

$$-20x=-32$$

Whakawehea ngā taha e rua ki te -20.

$$x=\frac{-32}{-20}$$

Whakahekea te hautanga \frac{-32}{-20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -4.

$$x=\frac{8}{5}$$
