Kua tāruatia ki te papatopenga
x_{2}x-7-2x=0
Tangohia te 2x mai i ngā taha e rua.
x_{2}x-2x=7
Me tāpiri te 7 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
\left(x_{2}-2\right)x=7
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(x_{2}-2\right)x}{x_{2}-2}=\frac{7}{x_{2}-2}
Whakawehea ngā taha e rua ki te x_{2}-2.
x=\frac{7}{x_{2}-2}
Mā te whakawehe ki te x_{2}-2 ka wetekia te whakareanga ki te x_{2}-2.
x_{2}x=2x+7
Me tāpiri te 7 ki ngā taha e rua.
xx_{2}=2x+7
He hanga arowhānui tō te whārite.
\frac{xx_{2}}{x}=\frac{2x+7}{x}
Whakawehea ngā taha e rua ki te x.
x_{2}=\frac{2x+7}{x}
Mā te whakawehe ki te x ka wetekia te whakareanga ki te x.
x_{2}=2+\frac{7}{x}
Whakawehe 2x+7 ki te x.
