Kua tāruatia ki te papatopenga
2x-5-5x=-16
Tangohia te 5x mai i ngā taha e rua.
-3x-5=-16
Pahekotia te 2x me -5x, ka -3x.
-3x=-16+5
Me tāpiri te 5 ki ngā taha e rua.
-3x=-11
Tāpirihia te -16 ki te 5, ka -11.
x=\frac{-11}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{11}{3}
Ka taea te hautanga \frac{-11}{-3} te whakamāmā ki te \frac{11}{3} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
