Kua tāruatia ki te papatopenga
7xy=2+8y
Me tāpiri te 8y ki ngā taha e rua.
7yx=8y+2
He hanga arowhānui tō te whārite.
\frac{7yx}{7y}=\frac{8y+2}{7y}
Whakawehea ngā taha e rua ki te 7y.
x=\frac{8y+2}{7y}
Mā te whakawehe ki te 7y ka wetekia te whakareanga ki te 7y.
x=\frac{8}{7}+\frac{2}{7y}
Whakawehe 2+8y ki te 7y.
\left(7x-8\right)y=2
Pahekotia ngā kīanga tau katoa e whai ana i te y.
\frac{\left(7x-8\right)y}{7x-8}=\frac{2}{7x-8}
Whakawehea ngā taha e rua ki te 7x-8.
y=\frac{2}{7x-8}
Mā te whakawehe ki te 7x-8 ka wetekia te whakareanga ki te 7x-8.
