Kua tāruatia ki te papatopenga
\sqrt{x-9}-5-\left(-5\right)=3-\left(-5\right)
Me tāpiri 5 ki ngā taha e rua o te whārite.
\sqrt{x-9}=3-\left(-5\right)
Mā te tango i te -5 i a ia ake anō ka toe ko te 0.
\sqrt{x-9}=8
Tango -5 mai i 3.
x-9=64
Pūruatia ngā taha e rua o te whārite.
x-9-\left(-9\right)=64-\left(-9\right)
Me tāpiri 9 ki ngā taha e rua o te whārite.
x=64-\left(-9\right)
Mā te tango i te -9 i a ia ake anō ka toe ko te 0.
x=73
Tango -9 mai i 64.
