Whakaoti i te -7-5x/2=13+5x/6

$$\frac { - 7 - 5 x } { 2 } = \frac { 13 + 5 x } { 6 }$$

Whakaoti mō x

$$x = -\frac{17}{10} = -1\frac{7}{10} = -1.7$$

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.

$$3\left(-7-5x\right)=13+5x$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te -7-5x.

$$-21-15x=13+5x$$

Tangohia te 5x mai i ngā taha e rua.

$$-21-15x-5x=13$$

Pahekotia te -15x me -5x, ka -20x.

$$-21-20x=13$$

Me tāpiri te 21 ki ngā taha e rua.

$$-20x=13+21$$

Tāpirihia te 13 ki te 21, ka 34.

$$-20x=34$$

Whakawehea ngā taha e rua ki te -20.

$$x=\frac{34}{-20}$$

Whakahekea te hautanga \frac{34}{-20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=-\frac{17}{10}$$
