3A+5B-A-4B=1100-600
Hei kimi i te tauaro o A+4B, kimihia te tauaro o ia taurangi.
2A+5B-4B=1100-600
Pahekotia te 3A me -A, ka 2A.
2A+B=1100-600
Pahekotia te 5B me -4B, ka B.
2A+B=500
Tangohia te 600 i te 1100, ka 500.
2A=500-B
Tangohia te B mai i ngā taha e rua.
\frac{2A}{2}=\frac{500-B}{2}
Whakawehea ngā taha e rua ki te 2.
A=\frac{500-B}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
A=-\frac{B}{2}+250
Whakawehe 500-B ki te 2.
3A+5B-A-4B=1100-600
Hei kimi i te tauaro o A+4B, kimihia te tauaro o ia taurangi.
2A+5B-4B=1100-600
