Pātaitai
Linear Equation
- 5 w + 1 = 2
Tohaina
Kua tāruatia ki te papatopenga
-5w=2-1
Tangohia te 1 mai i ngā taha e rua.
-5w=1
Tangohia te 1 i te 2, ka 1.
w=\frac{1}{-5}
Whakawehea ngā taha e rua ki te -5.
w=-\frac{1}{5}
Ka taea te hautanga \frac{1}{-5} te tuhi anō ko -\frac{1}{5} mā te tango i te tohu tōraro.
