Linear Equation
5 raruraru e ōrite ana ki:
\frac{ 3n }{ 14 } + \frac{ n }{ 2 } = \frac{ 2 }{ 7 }
Tohaina
Kua tāruatia ki te papatopenga
3n+7n=4
Me whakarea ngā taha e rua o te whārite ki te 14, arā, te tauraro pātahi he tino iti rawa te kitea o 14,2,7.
10n=4
Pahekotia te 3n me 7n, ka 10n.
n=\frac{4}{10}
Whakawehea ngā taha e rua ki te 10.
n=\frac{2}{5}
Whakahekea te hautanga \frac{4}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
