52-x+0=19x
Whakareatia te 0 ki te 2, ka 0.
52-x=19x
Tāpirihia te 52 ki te 0, ka 52.
52-x-19x=0
Tangohia te 19x mai i ngā taha e rua.
52-20x=0
Pahekotia te -x me -19x, ka -20x.
-20x=-52
Tangohia te 52 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-52}{-20}
Whakawehea ngā taha e rua ki te -20.
x=\frac{13}{5}
Whakahekea te hautanga \frac{-52}{-20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -4.
