Whakaoti i te 6(4-y)=3(2y+1)

$$6 ( 4 - y ) = 3 ( 2 y + 1 )$$

Whakaoti mō y

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

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te 4-y.

$$24-6y=3\left(2y+1\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2y+1.

$$24-6y=6y+3$$

Tangohia te 6y mai i ngā taha e rua.

$$24-6y-6y=3$$

Pahekotia te -6y me -6y, ka -12y.

$$24-12y=3$$

Tangohia te 24 mai i ngā taha e rua.

$$-12y=3-24$$

Tangohia te 24 i te 3, ka -21.

$$-12y=-21$$

Whakawehea ngā taha e rua ki te -12.

$$y=\frac{-21}{-12}$$

Whakahekea te hautanga \frac{-21}{-12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -3.

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