14b=378-8v
Tangohia te 8v mai i ngā taha e rua.
\frac{14b}{14}=\frac{378-8v}{14}
Whakawehea ngā taha e rua ki te 14.
b=\frac{378-8v}{14}
Mā te whakawehe ki te 14 ka wetekia te whakareanga ki te 14.
b=-\frac{4v}{7}+27
Whakawehe 378-8v ki te 14.
8v=378-14b
Tangohia te 14b mai i ngā taha e rua.
\frac{8v}{8}=\frac{378-14b}{8}
Whakawehea ngā taha e rua ki te 8.
v=\frac{378-14b}{8}
Mā te whakawehe ki te 8 ka wetekia te whakareanga ki te 8.
v=\frac{189-7b}{4}
Whakawehe 378-14b ki te 8.
