Kua tāruatia ki te papatopenga
5x-4=36
Pūruatia ngā taha e rua o te whārite.
5x-4-\left(-4\right)=36-\left(-4\right)
Me tāpiri 4 ki ngā taha e rua o te whārite.
5x=36-\left(-4\right)
Mā te tango i te -4 i a ia ake anō ka toe ko te 0.
5x=40
Tango -4 mai i 36.
\frac{5x}{5}=\frac{40}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{40}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
x=8
Whakawehe 40 ki te 5.
