x-8xy=-7
Tangohia te 8xy mai i ngā taha e rua.
\left(1-8y\right)x=-7
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(1-8y\right)x}{1-8y}=-\frac{7}{1-8y}
Whakawehea ngā taha e rua ki te -8y+1.
x=-\frac{7}{1-8y}
Mā te whakawehe ki te -8y+1 ka wetekia te whakareanga ki te -8y+1.
8xy-7=x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
8xy=x+7
Me tāpiri te 7 ki ngā taha e rua.
\frac{8xy}{8x}=\frac{x+7}{8x}
Whakawehea ngā taha e rua ki te 8x.
y=\frac{x+7}{8x}
Mā te whakawehe ki te 8x ka wetekia te whakareanga ki te 8x.
y=\frac{1}{8}+\frac{7}{8x}
Whakawehe x+7 ki te 8x.
