Kua tāruatia ki te papatopenga
64\left(0.5-y\right)+56y=35.84
Whakareatia ngā taha e rua o te whārite ki te 56.
32-64y+56y=35.84
Whakamahia te āhuatanga tohatoha hei whakarea te 64 ki te 0.5-y.
32-8y=35.84
Pahekotia te -64y me 56y, ka -8y.
-8y=35.84-32
Tangohia te 32 mai i ngā taha e rua.
-8y=3.84
Tangohia te 32 i te 35.84, ka 3.84.
y=\frac{3.84}{-8}
Whakawehea ngā taha e rua ki te -8.
y=\frac{384}{-800}
Whakarohaina te \frac{3.84}{-8} mā te whakarea i te taurunga me te tauraro ki te 100.
y=-\frac{12}{25}
Whakahekea te hautanga \frac{384}{-800} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 32.
