Kua tāruatia ki te papatopenga
12x=36+9y
Me tāpiri te 9y ki ngā taha e rua.
12x=9y+36
He hanga arowhānui tō te whārite.
\frac{12x}{12}=\frac{9y+36}{12}
Whakawehea ngā taha e rua ki te 12.
x=\frac{9y+36}{12}
Mā te whakawehe ki te 12 ka wetekia te whakareanga ki te 12.
x=\frac{3y}{4}+3
Whakawehe 36+9y ki te 12.
-9y=36-12x
Tangohia te 12x mai i ngā taha e rua.
\frac{-9y}{-9}=\frac{36-12x}{-9}
Whakawehea ngā taha e rua ki te -9.
y=\frac{36-12x}{-9}
Mā te whakawehe ki te -9 ka wetekia te whakareanga ki te -9.
y=\frac{4x}{3}-4
Whakawehe 36-12x ki te -9.
