Kua tāruatia ki te papatopenga
-3x=18-4y
Tangohia te 4y mai i ngā taha e rua.
\frac{-3x}{-3}=\frac{18-4y}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{18-4y}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
x=\frac{4y}{3}-6
Whakawehe 18-4y ki te -3.
4y=18+3x
Me tāpiri te 3x ki ngā taha e rua.
4y=3x+18
He hanga arowhānui tō te whārite.
\frac{4y}{4}=\frac{3x+18}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{3x+18}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
y=\frac{3x}{4}+\frac{9}{2}
Whakawehe 18+3x ki te 4.
