8x+4 \geq 16+8-3x
Tohaina
Kua tāruatia ki te papatopenga
8x+4\geq 24-3x
Tāpirihia te 16 ki te 8, ka 24.
8x+4+3x\geq 24
Me tāpiri te 3x ki ngā taha e rua.
11x+4\geq 24
Pahekotia te 8x me 3x, ka 11x.
11x\geq 24-4
Tangohia te 4 mai i ngā taha e rua.
11x\geq 20
Tangohia te 4 i te 24, ka 20.
x\geq \frac{20}{11}
Whakawehea ngā taha e rua ki te 11. I te mea he tōrunga te 11, kāore e huri te ahunga koreōrite.
