Kua tāruatia ki te papatopenga
-7x=14+2y
Me tāpiri te 2y ki ngā taha e rua.
-7x=2y+14
He hanga arowhānui tō te whārite.
\frac{-7x}{-7}=\frac{2y+14}{-7}
Whakawehea ngā taha e rua ki te -7.
x=\frac{2y+14}{-7}
Mā te whakawehe ki te -7 ka wetekia te whakareanga ki te -7.
x=-\frac{2y}{7}-2
Whakawehe 14+2y ki te -7.
-2y=14+7x
Me tāpiri te 7x ki ngā taha e rua.
-2y=7x+14
He hanga arowhānui tō te whārite.
\frac{-2y}{-2}=\frac{7x+14}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{7x+14}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=-\frac{7x}{2}-7
Whakawehe 14+7x ki te -2.
