Tohaina
Kua tāruatia ki te papatopenga
3w-5=16
Pūruatia ngā taha e rua o te whārite.
3w-5-\left(-5\right)=16-\left(-5\right)
Me tāpiri 5 ki ngā taha e rua o te whārite.
3w=16-\left(-5\right)
Mā te tango i te -5 i a ia ake anō ka toe ko te 0.
3w=21
Tango -5 mai i 16.
\frac{3w}{3}=\frac{21}{3}
Whakawehea ngā taha e rua ki te 3.
w=\frac{21}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
w=7
Whakawehe 21 ki te 3.
