Tohaina
Kua tāruatia ki te papatopenga
4x=240-3y
Tangohia te 3y mai i ngā taha e rua.
\frac{4x}{4}=\frac{240-3y}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{240-3y}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=-\frac{3y}{4}+60
Whakawehe 240-3y ki te 4.
3y=240-4x
Tangohia te 4x mai i ngā taha e rua.
\frac{3y}{3}=\frac{240-4x}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{240-4x}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
y=-\frac{4x}{3}+80
Whakawehe 240-4x ki te 3.
