Kua tāruatia ki te papatopenga
28\times 3-\left(x+3\right)<4x+4
Whakareatia ngā taha e rua o te whārite ki te 4. I te mea he tōrunga te 4, kāore e huri te ahunga koreōrite.
84-\left(x+3\right)<4x+4
Whakareatia te 28 ki te 3, ka 84.
84-x-3<4x+4
Hei kimi i te tauaro o x+3, kimihia te tauaro o ia taurangi.
81-x<4x+4
Tangohia te 3 i te 84, ka 81.
81-x-4x<4
Tangohia te 4x mai i ngā taha e rua.
81-5x<4
Pahekotia te -x me -4x, ka -5x.
-5x<4-81
Tangohia te 81 mai i ngā taha e rua.
-5x<-77
Tangohia te 81 i te 4, ka -77.
x>\frac{-77}{-5}
Whakawehea ngā taha e rua ki te -5. I te mea he tōraro a -5, ka huri te ahunga koreōrite.
x>\frac{77}{5}
Ka taea te hautanga \frac{-77}{-5} te whakamāmā ki te \frac{77}{5} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
