Kua tāruatia ki te papatopenga
-2x=9+3y
Me tāpiri te 3y ki ngā taha e rua.
-2x=3y+9
He hanga arowhānui tō te whārite.
\frac{-2x}{-2}=\frac{3y+9}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{3y+9}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=\frac{-3y-9}{2}
Whakawehe 9+3y ki te -2.
-3y=9+2x
Me tāpiri te 2x ki ngā taha e rua.
-3y=2x+9
He hanga arowhānui tō te whārite.
\frac{-3y}{-3}=\frac{2x+9}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{2x+9}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=-\frac{2x}{3}-3
Whakawehe 9+2x ki te -3.
