Kua tāruatia ki te papatopenga
2x-35=60x-4\times 2x
Me whakarea ngā taha e rua o te whārite ki te 20, arā, te tauraro pātahi he tino iti rawa te kitea o 10,4,5.
2x-35=60x-8x
Whakareatia te -4 ki te 2, ka -8.
2x-35=52x
Pahekotia te 60x me -8x, ka 52x.
2x-35-52x=0
Tangohia te 52x mai i ngā taha e rua.
-50x-35=0
Pahekotia te 2x me -52x, ka -50x.
-50x=35
Me tāpiri te 35 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{35}{-50}
Whakawehea ngā taha e rua ki te -50.
x=-\frac{7}{10}
Whakahekea te hautanga \frac{35}{-50} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
