Kua tāruatia ki te papatopenga
3x=10.5-y
Tangohia te y mai i ngā taha e rua.
\frac{3x}{3}=\frac{10.5-y}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{10.5-y}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
x=-\frac{y}{3}+\frac{7}{2}
Whakawehe 10.5-y ki te 3.
y=10.5-3x
Tangohia te 3x mai i ngā taha e rua.
