Whakaoti i te 9y+2/2=7y-4/6+5

$$\frac { 9 y + 2 } { 2 } = \frac { 7 y - 4 } { 6 } + 5$$

Whakaoti mō y

$$y=1$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,6.

$$3\left(9y+2\right)=7y-4+30$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 9y+2.

$$27y+6=7y-4+30$$

Tāpirihia te -4 ki te 30, ka 26.

$$27y+6=7y+26$$

Tangohia te 7y mai i ngā taha e rua.

$$27y+6-7y=26$$

Pahekotia te 27y me -7y, ka 20y.

$$20y+6=26$$

Tangohia te 6 mai i ngā taha e rua.

$$20y=26-6$$

Tangohia te 6 i te 26, ka 20.

$$20y=20$$

Whakawehea ngā taha e rua ki te 20.

$$y=\frac{20}{20}$$

Whakawehea te 20 ki te 20, kia riro ko 1.

$$y=1$$
