Whakaoti i te 2y+5/8+y/6=3.5+y/12

$$\frac { 2 y + 5 } { 8 } + \frac { y } { 6 } = \frac { 3.5 + y } { 12 }$$

Whakaoti mō y

$$y=-1$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 24, arā, te tauraro pātahi he tino iti rawa te kitea o 8,6,12.

$$3\left(2y+5\right)+4y=2\left(3.5+y\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2y+5.

$$6y+15+4y=2\left(3.5+y\right)$$

Pahekotia te 6y me 4y, ka 10y.

$$10y+15=2\left(3.5+y\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 3.5+y.

$$10y+15=7+2y$$

Tangohia te 2y mai i ngā taha e rua.

$$10y+15-2y=7$$

Pahekotia te 10y me -2y, ka 8y.

$$8y+15=7$$

Tangohia te 15 mai i ngā taha e rua.

$$8y=7-15$$

Tangohia te 15 i te 7, ka -8.

$$8y=-8$$

Whakawehea ngā taha e rua ki te 8.

$$y=\frac{-8}{8}$$

Whakawehea te -8 ki te 8, kia riro ko -1.

$$y=-1$$
