Kua tāruatia ki te papatopenga
45m=15+15z
Me tāpiri te 15z ki ngā taha e rua.
45m=15z+15
He hanga arowhānui tō te whārite.
\frac{45m}{45}=\frac{15z+15}{45}
Whakawehea ngā taha e rua ki te 45.
m=\frac{15z+15}{45}
Mā te whakawehe ki te 45 ka wetekia te whakareanga ki te 45.
m=\frac{z+1}{3}
Whakawehe 15+15z ki te 45.
-15z=15-45m
Tangohia te 45m mai i ngā taha e rua.
\frac{-15z}{-15}=\frac{15-45m}{-15}
Whakawehea ngā taha e rua ki te -15.
z=\frac{15-45m}{-15}
Mā te whakawehe ki te -15 ka wetekia te whakareanga ki te -15.
z=3m-1
Whakawehe 15-45m ki te -15.
