40x=2900-15y
Tangohia te 15y mai i ngā taha e rua.
\frac{40x}{40}=\frac{2900-15y}{40}
Whakawehea ngā taha e rua ki te 40.
x=\frac{2900-15y}{40}
Mā te whakawehe ki te 40 ka wetekia te whakareanga ki te 40.
x=-\frac{3y}{8}+\frac{145}{2}
Whakawehe 2900-15y ki te 40.
15y=2900-40x
Tangohia te 40x mai i ngā taha e rua.
\frac{15y}{15}=\frac{2900-40x}{15}
Whakawehea ngā taha e rua ki te 15.
y=\frac{2900-40x}{15}
Mā te whakawehe ki te 15 ka wetekia te whakareanga ki te 15.
y=\frac{580-8x}{3}
Whakawehe 2900-40x ki te 15.
