Kua tāruatia ki te papatopenga
7x=14+y
Me tāpiri te y ki ngā taha e rua.
7x=y+14
He hanga arowhānui tō te whārite.
\frac{7x}{7}=\frac{y+14}{7}
Whakawehea ngā taha e rua ki te 7.
x=\frac{y+14}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
x=\frac{y}{7}+2
Whakawehe 14+y ki te 7.
-y=14-7x
Tangohia te 7x mai i ngā taha e rua.
\frac{-y}{-1}=\frac{14-7x}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{14-7x}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=7x-14
Whakawehe 14-7x ki te -1.
