Whakaoti i te 5(2x-8)geq3(x+5)

$$5 ( 2 x - 8 ) \geq 3 ( x + 5 )$$

Whakaoti mō x

$$x\geq \frac{55}{7}$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 2x-8.

$$10x-40\geq 3\left(x+5\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+5.

$$10x-40\geq 3x+15$$

Tangohia te 3x mai i ngā taha e rua.

$$10x-40-3x\geq 15$$

Pahekotia te 10x me -3x, ka 7x.

$$7x-40\geq 15$$

Me tāpiri te 40 ki ngā taha e rua.

$$7x\geq 15+40$$

Tāpirihia te 15 ki te 40, ka 55.

$$7x\geq 55$$

Whakawehea ngā taha e rua ki te 7. I te mea he tōrunga te 7, kāore e huri te ahunga koreōrite.

$$x\geq \frac{55}{7}$$
