Whakaoti mō x, y, z, a
a=4
Tohaina
Kua tāruatia ki te papatopenga
-3x=5-6
Whakaarohia te whārite tuatahi. Tangohia te 6 mai i ngā taha e rua.
-3x=-1
Tangohia te 6 i te 5, ka -1.
x=\frac{-1}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{1}{3}
Ka taea te hautanga \frac{-1}{-3} te whakamāmā ki te \frac{1}{3} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
x=\frac{1}{3} y=4 z=4 a=4
Kua oti te pūnaha te whakatau.
Ngā Tauira
