Kua tāruatia ki te papatopenga
-7x=-2+6y
Me tāpiri te 6y ki ngā taha e rua.
-7x=6y-2
He hanga arowhānui tō te whārite.
\frac{-7x}{-7}=\frac{6y-2}{-7}
Whakawehea ngā taha e rua ki te -7.
x=\frac{6y-2}{-7}
Mā te whakawehe ki te -7 ka wetekia te whakareanga ki te -7.
x=\frac{2-6y}{7}
Whakawehe -2+6y ki te -7.
-6y=-2+7x
Me tāpiri te 7x ki ngā taha e rua.
-6y=7x-2
He hanga arowhānui tō te whārite.
\frac{-6y}{-6}=\frac{7x-2}{-6}
Whakawehea ngā taha e rua ki te -6.
y=\frac{7x-2}{-6}
Mā te whakawehe ki te -6 ka wetekia te whakareanga ki te -6.
y=-\frac{7x}{6}+\frac{1}{3}
Whakawehe -2+7x ki te -6.
