5-8x-5x=13
Tangohia te 5x mai i ngā taha e rua.
5-13x=13
Pahekotia te -8x me -5x, ka -13x.
-13x=13-5
Tangohia te 5 mai i ngā taha e rua.
-13x=8
Tangohia te 5 i te 13, ka 8.
x=\frac{8}{-13}
Whakawehea ngā taha e rua ki te -13.
x=-\frac{8}{13}
Ka taea te hautanga \frac{8}{-13} te tuhi anō ko -\frac{8}{13} mā te tango i te tohu tōraro.
