Tohaina
Kua tāruatia ki te papatopenga
2x=50-7y
Tangohia te 7y mai i ngā taha e rua.
\frac{2x}{2}=\frac{50-7y}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{50-7y}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=-\frac{7y}{2}+25
Whakawehe 50-7y ki te 2.
7y=50-2x
Tangohia te 2x mai i ngā taha e rua.
\frac{7y}{7}=\frac{50-2x}{7}
Whakawehea ngā taha e rua ki te 7.
y=\frac{50-2x}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
