Whakaoti mō x
x = -\frac{12}{5} = -2\frac{2}{5} = -2.4
Graph
Tohaina
Kua tāruatia ki te papatopenga
-5x=9+3
Me tāpiri te 3 ki ngā taha e rua.
-5x=12
Tāpirihia te 9 ki te 3, ka 12.
x=\frac{12}{-5}
Whakawehea ngā taha e rua ki te -5.
x=-\frac{12}{5}
Ka taea te hautanga \frac{12}{-5} te tuhi anō ko -\frac{12}{5} mā te tango i te tohu tōraro.
