xy+1=5-y
Tangohia te y mai i ngā taha e rua.
xy=5-y-1
Tangohia te 1 mai i ngā taha e rua.
xy=4-y
Tangohia te 1 i te 5, ka 4.
yx=4-y
He hanga arowhānui tō te whārite.
\frac{yx}{y}=\frac{4-y}{y}
Whakawehea ngā taha e rua ki te y.
x=\frac{4-y}{y}
Mā te whakawehe ki te y ka wetekia te whakareanga ki te y.
x=-1+\frac{4}{y}
Whakawehe 4-y ki te y.
xy+y=5-1
Tangohia te 1 mai i ngā taha e rua.
xy+y=4
Tangohia te 1 i te 5, ka 4.
\left(x+1\right)y=4
Pahekotia ngā kīanga tau katoa e whai ana i te y.
\frac{\left(x+1\right)y}{x+1}=\frac{4}{x+1}
Whakawehea ngā taha e rua ki te x+1.
y=\frac{4}{x+1}
Mā te whakawehe ki te x+1 ka wetekia te whakareanga ki te x+1.
