5ab+20-3ab=0
Tangohia te 3ab mai i ngā taha e rua.
2ab+20=0
Pahekotia te 5ab me -3ab, ka 2ab.
2ab=-20
Tangohia te 20 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
2ba=-20
He hanga arowhānui tō te whārite.
\frac{2ba}{2b}=-\frac{20}{2b}
Whakawehea ngā taha e rua ki te 2b.
a=-\frac{20}{2b}
Mā te whakawehe ki te 2b ka wetekia te whakareanga ki te 2b.
a=-\frac{10}{b}
Whakawehe -20 ki te 2b.
5ab+20-3ab=0
Tangohia te 3ab mai i ngā taha e rua.
2ab+20=0
Pahekotia te 5ab me -3ab, ka 2ab.
2ab=-20
Tangohia te 20 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\frac{2ab}{2a}=-\frac{20}{2a}
Whakawehea ngā taha e rua ki te 2a.
b=-\frac{20}{2a}
Mā te whakawehe ki te 2a ka wetekia te whakareanga ki te 2a.
b=-\frac{10}{a}
Whakawehe -20 ki te 2a.
