Whakaoti i te 2(2t-3)leq23(t-1)

$$2 ( 2 t - 3 ) \leq 23 ( t - 1 )$$

Whakaoti mō t

$$t\geq \frac{17}{19}$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2t-3.

$$4t-6\leq 23\left(t-1\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 23 ki te t-1.

$$4t-6\leq 23t-23$$

Tangohia te 23t mai i ngā taha e rua.

$$4t-6-23t\leq -23$$

Pahekotia te 4t me -23t, ka -19t.

$$-19t-6\leq -23$$

Me tāpiri te 6 ki ngā taha e rua.

$$-19t\leq -23+6$$

Tāpirihia te -23 ki te 6, ka -17.

$$-19t\leq -17$$

Whakawehea ngā taha e rua ki te -19. I te mea he tōraro a -19, ka huri te ahunga koreōrite.

$$t\geq \frac{-17}{-19}$$

Ka taea te hautanga \frac{-17}{-19} te whakamāmā ki te \frac{17}{19} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$t\geq \frac{17}{19}$$
