-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=1
Tangohia te 12 i te 13, ka 1.
x=\frac{1}{-26}
Whakawehea ngā taha e rua ki te -26.
x=-\frac{1}{26}
Ka taea te hautanga \frac{1}{-26} te tuhi anō ko -\frac{1}{26} mā te tango i te tohu tōraro.
