Whakaoti i te 2(4x-3)=5(2x-5)

$$2 ( 4 x - 3 ) = 5 ( 2 x - 5 )$$

Whakaoti mō x

$$x = \frac{19}{2} = 9\frac{1}{2} = 9.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 4x-3.

$$8x-6=5\left(2x-5\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 2x-5.

$$8x-6=10x-25$$

Tangohia te 10x mai i ngā taha e rua.

$$8x-6-10x=-25$$

Pahekotia te 8x me -10x, ka -2x.

$$-2x-6=-25$$

Me tāpiri te 6 ki ngā taha e rua.

$$-2x=-25+6$$

Tāpirihia te -25 ki te 6, ka -19.

$$-2x=-19$$

Whakawehea ngā taha e rua ki te -2.

$$x=\frac{-19}{-2}$$

Ka taea te hautanga \frac{-19}{-2} te whakamāmā ki te \frac{19}{2} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$x=\frac{19}{2}$$
