Kua tāruatia ki te papatopenga
10d=5.5-0.05n
Tangohia te 0.05n mai i ngā taha e rua.
10d=-\frac{n}{20}+5.5
He hanga arowhānui tō te whārite.
\frac{10d}{10}=\frac{-\frac{n}{20}+5.5}{10}
Whakawehea ngā taha e rua ki te 10.
d=\frac{-\frac{n}{20}+5.5}{10}
Mā te whakawehe ki te 10 ka wetekia te whakareanga ki te 10.
d=-\frac{n}{200}+\frac{11}{20}
Whakawehe 5.5-\frac{n}{20} ki te 10.
0.05n=5.5-10d
Tangohia te 10d mai i ngā taha e rua.
\frac{0.05n}{0.05}=\frac{5.5-10d}{0.05}
Me whakarea ngā taha e rua ki te 20.
n=\frac{5.5-10d}{0.05}
Mā te whakawehe ki te 0.05 ka wetekia te whakareanga ki te 0.05.
n=110-200d
Whakawehe 5.5-10d ki te 0.05 mā te whakarea 5.5-10d ki te tau huripoki o 0.05.
