Whakaoti i te 0.05(x+60)-0.04(x-10)=3.3

$$0.05 ( x + 60 ) - 0.04 ( x - 10 ) = 3.3$$

Whakaoti mō x

$$x=-10$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 0.05 ki te x+60.

$$0.05x+3-0.04\left(x-10\right)=3.3$$

Whakamahia te āhuatanga tohatoha hei whakarea te -0.04 ki te x-10.

$$0.05x+3-0.04x+0.4=3.3$$

Pahekotia te 0.05x me -0.04x, ka 0.01x.

$$0.01x+3+0.4=3.3$$

Tāpirihia te 3 ki te 0.4, ka 3.4.

$$0.01x+3.4=3.3$$

Tangohia te 3.4 mai i ngā taha e rua.

$$0.01x=3.3-3.4$$

Tangohia te 3.4 i te 3.3, ka -0.1.

$$0.01x=-0.1$$

Whakawehea ngā taha e rua ki te 0.01.

$$x=\frac{-0.1}{0.01}$$

Whakarohaina te \frac{-0.1}{0.01} mā te whakarea i te taurunga me te tauraro ki te 100. Ka whakawehea he tau ki te tahi, hua ai ko ia anō.

$$x=-10$$
