Kua tāruatia ki te papatopenga
-4x=18+9y
Me tāpiri te 9y ki ngā taha e rua.
-4x=9y+18
He hanga arowhānui tō te whārite.
\frac{-4x}{-4}=\frac{9y+18}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{9y+18}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
x=-\frac{9y}{4}-\frac{9}{2}
Whakawehe 18+9y ki te -4.
-9y=18+4x
Me tāpiri te 4x ki ngā taha e rua.
-9y=4x+18
He hanga arowhānui tō te whārite.
\frac{-9y}{-9}=\frac{4x+18}{-9}
Whakawehea ngā taha e rua ki te -9.
y=\frac{4x+18}{-9}
Mā te whakawehe ki te -9 ka wetekia te whakareanga ki te -9.
y=-\frac{4x}{9}-2
Whakawehe 18+4x ki te -9.
