Whakaoti i te 3x/4-1/5+2x=5/4-3x/20

$$\frac{ 3x }{ 4 } - \frac{ 1 }{ 5 } +2x= \frac{ 5 }{ 4 } - \frac{ 3x }{ 20 }$$

Whakaoti mō x

$$x=\frac{1}{2}=0.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 20, arā, te tauraro pātahi he tino iti rawa te kitea o 4,5,20.

$$5\times 3x-4+40x=25-3x$$

Whakareatia te 5 ki te 3, ka 15.

$$15x-4+40x=25-3x$$

Pahekotia te 15x me 40x, ka 55x.

$$55x-4=25-3x$$

Me tāpiri te 3x ki ngā taha e rua.

$$55x-4+3x=25$$

Pahekotia te 55x me 3x, ka 58x.

$$58x-4=25$$

Me tāpiri te 4 ki ngā taha e rua.

$$58x=25+4$$

Tāpirihia te 25 ki te 4, ka 29.

$$58x=29$$

Whakawehea ngā taha e rua ki te 58.

$$x=\frac{29}{58}$$

Whakahekea te hautanga \frac{29}{58} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 29.

$$x=\frac{1}{2}$$
