0.2x-6=16x
Whakamahia te āhuatanga tohatoha hei whakarea te 0.2 ki te x-30.
0.2x-6-16x=0
Tangohia te 16x mai i ngā taha e rua.
-15.8x-6=0
Pahekotia te 0.2x me -16x, ka -15.8x.
-15.8x=6
Me tāpiri te 6 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{6}{-15.8}
Whakawehea ngā taha e rua ki te -15.8.
x=\frac{60}{-158}
Whakarohaina te \frac{6}{-15.8} mā te whakarea i te taurunga me te tauraro ki te 10.
x=-\frac{30}{79}
Whakahekea te hautanga \frac{60}{-158} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
