-5v+8-64v=-475
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te 1-8v.
-69v+8=-475
Pahekotia te -5v me -64v, ka -69v.
-69v=-475-8
Tangohia te 8 mai i ngā taha e rua.
-69v=-483
Tangohia te 8 i te -475, ka -483.
v=\frac{-483}{-69}
Whakawehea ngā taha e rua ki te -69.
v=7
Whakawehea te -483 ki te -69, kia riro ko 7.
