Tohaina
Kua tāruatia ki te papatopenga
-13.9x+12.5x=5.7
Me tāpiri te 12.5x ki ngā taha e rua.
-1.4x=5.7
Pahekotia te -13.9x me 12.5x, ka -1.4x.
x=\frac{5.7}{-1.4}
Whakawehea ngā taha e rua ki te -1.4.
x=\frac{57}{-14}
Whakarohaina te \frac{5.7}{-1.4} mā te whakarea i te taurunga me te tauraro ki te 10.
x=-\frac{57}{14}
Ka taea te hautanga \frac{57}{-14} te tuhi anō ko -\frac{57}{14} mā te tango i te tohu tōraro.
