Whakaoti i te (1/2x+5/12)-15/5=2/3

$$( \frac { 1 } { 2 } x + \frac { 5 } { 12 } ) - 1 \frac { 5 } { 5 } = \frac { 2 } { 3 }$$

Whakaoti mō x

$$x = \frac{9}{2} = 4\frac{1}{2} = 4.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 60, arā, te tauraro pātahi he tino iti rawa te kitea o 2,12,5,3.

$$30x+25-12\left(5+5\right)=40$$

Tāpirihia te 5 ki te 5, ka 10.

$$30x+25-12\times 10=40$$

Whakareatia te -12 ki te 10, ka -120.

$$30x+25-120=40$$

Tangohia te 120 i te 25, ka -95.

$$30x-95=40$$

Me tāpiri te 95 ki ngā taha e rua.

$$30x=40+95$$

Tāpirihia te 40 ki te 95, ka 135.

$$30x=135$$

Whakawehea ngā taha e rua ki te 30.

$$x=\frac{135}{30}$$

Whakahekea te hautanga \frac{135}{30} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 15.

$$x=\frac{9}{2}$$
