Kua tāruatia ki te papatopenga
3\sqrt{x}-12-\left(-12\right)=-\left(-12\right)
Me tāpiri 12 ki ngā taha e rua o te whārite.
3\sqrt{x}=-\left(-12\right)
Mā te tango i te -12 i a ia ake anō ka toe ko te 0.
3\sqrt{x}=12
Tango -12 mai i 0.
\frac{3\sqrt{x}}{3}=\frac{12}{3}
Whakawehea ngā taha e rua ki te 3.
\sqrt{x}=\frac{12}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
\sqrt{x}=4
Whakawehe 12 ki te 3.
x=16
Pūruatia ngā taha e rua o te whārite.
Ngā Tauira
