Whakaoti i te 6fgeq-4(-f-19)

$$6 f \geq - 4 ( - f - 19 )$$

Whakaoti mō f

$$f\geq 38$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te -f-19.

$$6f\geq -4\left(-f\right)+76$$

Whakareatia te -4 ki te -1, ka 4.

$$6f\geq 4f+76$$

Tangohia te 4f mai i ngā taha e rua.

$$6f-4f\geq 76$$

Pahekotia te 6f me -4f, ka 2f.

$$2f\geq 76$$

Whakawehea ngā taha e rua ki te 2. I te mea he tōrunga te 2, kāore e huri te ahunga koreōrite.

$$f\geq \frac{76}{2}$$

Whakawehea te 76 ki te 2, kia riro ko 38.

$$f\geq 38$$
