Whakaoti i te 3.5(0.1x+1)-4.1x=2.5(2-1.2x)

$$3.5 ( 0.1 x + 1 ) - 4.1 x = 2.5 ( 2 - 1.2 x )$$

Whakaoti mō x

$$x=-2$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 3.5 ki te 0.1x+1.

$$0.35x+3.5-4.1x=2.5\left(2-1.2x\right)$$

Pahekotia te 0.35x me -4.1x, ka -3.75x.

$$-3.75x+3.5=2.5\left(2-1.2x\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2.5 ki te 2-1.2x.

$$-3.75x+3.5=5-3x$$

Me tāpiri te 3x ki ngā taha e rua.

$$-3.75x+3.5+3x=5$$

Pahekotia te -3.75x me 3x, ka -0.75x.

$$-0.75x+3.5=5$$

Tangohia te 3.5 mai i ngā taha e rua.

$$-0.75x=5-3.5$$

Tangohia te 3.5 i te 5, ka 1.5.

$$-0.75x=1.5$$

Whakawehea ngā taha e rua ki te -0.75.

$$x=\frac{1.5}{-0.75}$$

Whakarohaina te \frac{1.5}{-0.75} mā te whakarea i te taurunga me te tauraro ki te 100.

$$x=\frac{150}{-75}$$

Whakawehea te 150 ki te -75, kia riro ko -2.

$$x=-2$$
