Linear Equation
5 raruraru e ōrite ana ki:
30 \cdot 8 = ( \frac { 2 \times 22 } { 7 } ) \times x
Tohaina
Kua tāruatia ki te papatopenga
210\times 8=2\times 22x
Whakareatia ngā taha e rua o te whārite ki te 7.
1680=2\times 22x
Whakareatia te 210 ki te 8, ka 1680.
1680=44x
Whakareatia te 2 ki te 22, ka 44.
44x=1680
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{1680}{44}
Whakawehea ngā taha e rua ki te 44.
x=\frac{420}{11}
Whakahekea te hautanga \frac{1680}{44} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
