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