121-6x-27.8x=0
Tangohia te 27.8x mai i ngā taha e rua.
121-33.8x=0
Pahekotia te -6x me -27.8x, ka -33.8x.
-33.8x=-121
Tangohia te 121 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-121}{-33.8}
Whakawehea ngā taha e rua ki te -33.8.
x=\frac{-1210}{-338}
Whakarohaina te \frac{-121}{-33.8} mā te whakarea i te taurunga me te tauraro ki te 10.
x=\frac{605}{169}
Whakahekea te hautanga \frac{-1210}{-338} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.
