-2x=14-7y
Tangohia te 7y mai i ngā taha e rua.
\frac{-2x}{-2}=\frac{14-7y}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{14-7y}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=\frac{7y}{2}-7
Whakawehe 14-7y ki te -2.
7y=14+2x
Me tāpiri te 2x ki ngā taha e rua.
7y=2x+14
He hanga arowhānui tō te whārite.
\frac{7y}{7}=\frac{2x+14}{7}
Whakawehea ngā taha e rua ki te 7.
y=\frac{2x+14}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
y=\frac{2x}{7}+2
Whakawehe 14+2x ki te 7.
