Kua tāruatia ki te papatopenga
-\left(8x-1\right)+4.5=-28.5
Whakareatia ngā taha e rua o te whārite ki te 3.
-8x-\left(-1\right)+4.5=-28.5
Hei kimi i te tauaro o 8x-1, kimihia te tauaro o ia taurangi.
-8x+1+4.5=-28.5
Ko te tauaro o -1 ko 1.
-8x+5.5=-28.5
Tāpirihia te 1 ki te 4.5, ka 5.5.
-8x=-28.5-5.5
Tangohia te 5.5 mai i ngā taha e rua.
-8x=-34
Tangohia te 5.5 i te -28.5, ka -34.
x=\frac{-34}{-8}
Whakawehea ngā taha e rua ki te -8.
x=\frac{17}{4}
Whakahekea te hautanga \frac{-34}{-8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.
