13x+45-2x=-1
Tangohia te 2x mai i ngā taha e rua.
11x+45=-1
Pahekotia te 13x me -2x, ka 11x.
11x=-1-45
Tangohia te 45 mai i ngā taha e rua.
11x=-46
Tangohia te 45 i te -1, ka -46.
x=\frac{-46}{11}
Whakawehea ngā taha e rua ki te 11.
x=-\frac{46}{11}
Ka taea te hautanga \frac{-46}{11} te tuhi anō ko -\frac{46}{11} mā te tango i te tohu tōraro.
