Kua tāruatia ki te papatopenga
-4x=-7+3y
Me tāpiri te 3y ki ngā taha e rua.
-4x=3y-7
He hanga arowhānui tō te whārite.
\frac{-4x}{-4}=\frac{3y-7}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{3y-7}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
x=\frac{7-3y}{4}
Whakawehe -7+3y ki te -4.
-3y=-7+4x
Me tāpiri te 4x ki ngā taha e rua.
-3y=4x-7
He hanga arowhānui tō te whārite.
\frac{-3y}{-3}=\frac{4x-7}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{4x-7}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{7-4x}{3}
Whakawehe -7+4x ki te -3.
