-x-10+8x>3\left(x-4\right)-\left(x-2\right)
Tangohia te 2 i te -8, ka -10.
-x-10+8x>3x-12-\left(x-2\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-4.
-x-10+8x>3x-12-x-\left(-2\right)
Hei kimi i te tauaro o x-2, kimihia te tauaro o ia taurangi.
-x-10+8x>3x-12-x+2
Ko te tauaro o -2 ko 2.
-x-10+8x>2x-12+2
Pahekotia te 3x me -x, ka 2x.
-x-10+8x>2x-10
Tāpirihia te -12 ki te 2, ka -10.
-x-10+8x-2x>-10
Tangohia te 2x mai i ngā taha e rua.
-x-10+6x>-10
Pahekotia te 8x me -2x, ka 6x.
-x+6x>-10+10
Me tāpiri te 10 ki ngā taha e rua.
-x+6x>0
Tāpirihia te -10 ki te 10, ka 0.
5x>0
Pahekotia te -x me 6x, ka 5x.
x>0
Ko te otinga o ngā tau e rua ko >0 ina ko >0 te rua, ko <0 rānei te rua. Ina ko 5>0, he >0 rawa a x.
