Kua tāruatia ki te papatopenga
-25-\left(x+4\right)>55-15x
Whakareatia ngā taha e rua o te whārite ki te 5. I te mea he tōrunga te 5, kāore e huri te ahunga koreōrite.
-25-x-4>55-15x
Hei kimi i te tauaro o x+4, kimihia te tauaro o ia taurangi.
-29-x>55-15x
Tangohia te 4 i te -25, ka -29.
-29-x+15x>55
Me tāpiri te 15x ki ngā taha e rua.
-29+14x>55
Pahekotia te -x me 15x, ka 14x.
14x>55+29
Me tāpiri te 29 ki ngā taha e rua.
14x>84
Tāpirihia te 55 ki te 29, ka 84.
x>\frac{84}{14}
Whakawehea ngā taha e rua ki te 14. I te mea he tōrunga te 14, kāore e huri te ahunga koreōrite.
x>6
Whakawehea te 84 ki te 14, kia riro ko 6.
