16x-1400-100=0
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 8x-700.
16x-1500=0
Tangohia te 100 i te -1400, ka -1500.
16x=1500
Me tāpiri te 1500 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{1500}{16}
Whakawehea ngā taha e rua ki te 16.
x=\frac{375}{4}
Whakahekea te hautanga \frac{1500}{16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
