Kua tāruatia ki te papatopenga
2ab-4=4b
Me tāpiri te 4b ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
2ab=4b+4
Me tāpiri te 4 ki ngā taha e rua.
2ba=4b+4
He hanga arowhānui tō te whārite.
\frac{2ba}{2b}=\frac{4b+4}{2b}
Whakawehea ngā taha e rua ki te 2b.
a=\frac{4b+4}{2b}
Mā te whakawehe ki te 2b ka wetekia te whakareanga ki te 2b.
a=2+\frac{2}{b}
Whakawehe 4+4b ki te 2b.
-4b+2ab=4
Me tāpiri te 4 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
\left(-4+2a\right)b=4
Pahekotia ngā kīanga tau katoa e whai ana i te b.
\left(2a-4\right)b=4
He hanga arowhānui tō te whārite.
\frac{\left(2a-4\right)b}{2a-4}=\frac{4}{2a-4}
Whakawehea ngā taha e rua ki te -4+2a.
b=\frac{4}{2a-4}
Mā te whakawehe ki te -4+2a ka wetekia te whakareanga ki te -4+2a.
b=\frac{2}{a-2}
Whakawehe 4 ki te -4+2a.
