2x+9-17x=-5
Tangohia te 17x mai i ngā taha e rua.
-15x+9=-5
Pahekotia te 2x me -17x, ka -15x.
-15x=-5-9
Tangohia te 9 mai i ngā taha e rua.
-15x=-14
Tangohia te 9 i te -5, ka -14.
x=\frac{-14}{-15}
Whakawehea ngā taha e rua ki te -15.
x=\frac{14}{15}
Ka taea te hautanga \frac{-14}{-15} te whakamāmā ki te \frac{14}{15} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
