-13x+12-13x=-13
Tangohia te 13x mai i ngā taha e rua.
-26x+12=-13
Pahekotia te -13x me -13x, ka -26x.
-26x=-13-12
Tangohia te 12 mai i ngā taha e rua.
-26x=-25
Tangohia te 12 i te -13, ka -25.
x=\frac{-25}{-26}
Whakawehea ngā taha e rua ki te -26.
x=\frac{25}{26}
Ka taea te hautanga \frac{-25}{-26} te whakamāmā ki te \frac{25}{26} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
