Kua tāruatia ki te papatopenga
2x=7+4y
Me tāpiri te 4y ki ngā taha e rua.
2x=4y+7
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{4y+7}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{4y+7}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=2y+\frac{7}{2}
Whakawehe 7+4y ki te 2.
-4y=7-2x
Tangohia te 2x mai i ngā taha e rua.
\frac{-4y}{-4}=\frac{7-2x}{-4}
Whakawehea ngā taha e rua ki te -4.
y=\frac{7-2x}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
y=\frac{x}{2}-\frac{7}{4}
Whakawehe 7-2x ki te -4.
