Whakaoti i te 8(x-1)+9>15(4-2x)-4

$$8 ( x - 1 ) + 9 > 15 ( 4 - 2 x ) - 4$$

Whakaoti mō x

$$x>\frac{55}{38}$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te x-1.

$$8x-8+9>15\left(4-2x\right)-4$$

Tāpirihia te -8 ki te 9, ka 1.

$$8x+1>15\left(4-2x\right)-4$$

Whakamahia te āhuatanga tohatoha hei whakarea te 15 ki te 4-2x.

$$8x+1>60-30x-4$$

Tangohia te 4 i te 60, ka 56.

$$8x+1>56-30x$$

Me tāpiri te 30x ki ngā taha e rua.

$$8x+1+30x>56$$

Pahekotia te 8x me 30x, ka 38x.

$$38x+1>56$$

Tangohia te 1 mai i ngā taha e rua.

$$38x>56-1$$

Tangohia te 1 i te 56, ka 55.

$$38x>55$$

Whakawehea ngā taha e rua ki te 38. I te mea he tōrunga te 38, kāore e huri te ahunga koreōrite.

$$x>\frac{55}{38}$$
