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