3b+0.4=0 3b+0.4=0
Tuhia te pūtakerua o ngā taha e rua o te whārite.
3b+0.4-0.4=-0.4 3b+0.4-0.4=-0.4
Me tango 0.4 mai i ngā taha e rua o te whārite.
3b=-0.4 3b=-0.4
Mā te tango i te 0.4 i a ia ake anō ka toe ko te 0.
3b=-0.4
Tango 0.4 mai i 0.
\frac{3b}{3}=-\frac{0.4}{3} \frac{3b}{3}=-\frac{0.4}{3}
Whakawehea ngā taha e rua ki te 3.
b=-\frac{0.4}{3} b=-\frac{0.4}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
b=-\frac{2}{15}
Whakawehe -0.4 ki te 3.
