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