-2-7+56y=-2
Whakamahia te āhuatanga tohatoha hei whakarea te -7 ki te 1-8y.
-9+56y=-2
Tangohia te 7 i te -2, ka -9.
56y=-2+9
Me tāpiri te 9 ki ngā taha e rua.
56y=7
Tāpirihia te -2 ki te 9, ka 7.
y=\frac{7}{56}
Whakawehea ngā taha e rua ki te 56.
y=\frac{1}{8}
Whakahekea te hautanga \frac{7}{56} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 7.
