Tohaina
Kua tāruatia ki te papatopenga
4a-13=6
Pūruatia ngā taha e rua o te whārite.
4a-13-\left(-13\right)=6-\left(-13\right)
Me tāpiri 13 ki ngā taha e rua o te whārite.
4a=6-\left(-13\right)
Mā te tango i te -13 i a ia ake anō ka toe ko te 0.
4a=19
Tango -13 mai i 6.
\frac{4a}{4}=\frac{19}{4}
Whakawehea ngā taha e rua ki te 4.
a=\frac{19}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
