Kua tāruatia ki te papatopenga
7x=-17+y
Me tāpiri te y ki ngā taha e rua.
7x=y-17
He hanga arowhānui tō te whārite.
\frac{7x}{7}=\frac{y-17}{7}
Whakawehea ngā taha e rua ki te 7.
x=\frac{y-17}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
-y=-17-7x
Tangohia te 7x mai i ngā taha e rua.
-y=-7x-17
He hanga arowhānui tō te whārite.
\frac{-y}{-1}=\frac{-7x-17}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{-7x-17}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=7x+17
Whakawehe -17-7x ki te -1.
