Tohaina
Kua tāruatia ki te papatopenga
x+y=30-x
Tangohia te 5 i te 35, ka 30.
x+y+x=30
Me tāpiri te x ki ngā taha e rua.
2x+y=30
Pahekotia te x me x, ka 2x.
2x=30-y
Tangohia te y mai i ngā taha e rua.
\frac{2x}{2}=\frac{30-y}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{30-y}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=-\frac{y}{2}+15
Whakawehe 30-y ki te 2.
x+y=30-x
Tangohia te 5 i te 35, ka 30.
y=30-x-x
Tangohia te x mai i ngā taha e rua.
y=30-2x
Pahekotia te -x me -x, ka -2x.
