0.55y+7=8.75+0.35y
Whakamahia te āhuatanga tohatoha hei whakarea te 0.35 ki te 25+y.
0.55y+7-0.35y=8.75
Tangohia te 0.35y mai i ngā taha e rua.
0.2y+7=8.75
Pahekotia te 0.55y me -0.35y, ka 0.2y.
0.2y=8.75-7
Tangohia te 7 mai i ngā taha e rua.
0.2y=1.75
Tangohia te 7 i te 8.75, ka 1.75.
y=\frac{1.75}{0.2}
Whakawehea ngā taha e rua ki te 0.2.
y=\frac{175}{20}
Whakarohaina te \frac{1.75}{0.2} mā te whakarea i te taurunga me te tauraro ki te 100.
y=\frac{35}{4}
Whakahekea te hautanga \frac{175}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
