Whakaoti i te 4x/5+1/5+9=5x/6-7/5

$$\frac { 4 x } { 5 } + \frac { 1 } { 5 } + 9 = \frac { 5 x } { 6 } - \frac { 7 } { 5 }$$

Whakaoti mō x

$$x=318$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 30, arā, te tauraro pātahi he tino iti rawa te kitea o 5,6.

$$6\times 4x+6+270=5\times 5x-42$$

Whakareatia te 6 ki te 4, ka 24.

$$24x+6+270=5\times 5x-42$$

Tāpirihia te 6 ki te 270, ka 276.

$$24x+276=5\times 5x-42$$

Whakareatia te 5 ki te 5, ka 25.

$$24x+276=25x-42$$

Tangohia te 25x mai i ngā taha e rua.

$$24x+276-25x=-42$$

Pahekotia te 24x me -25x, ka -x.

$$-x+276=-42$$

Tangohia te 276 mai i ngā taha e rua.

$$-x=-42-276$$

Tangohia te 276 i te -42, ka -318.

$$-x=-318$$

Me whakarea ngā taha e rua ki te -1.

$$x=318$$
