16+2x=-13x
Tangohia te 7 i te 23, ka 16.
16+2x+13x=0
Me tāpiri te 13x ki ngā taha e rua.
16+15x=0
Pahekotia te 2x me 13x, ka 15x.
15x=-16
Tangohia te 16 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-16}{15}
Whakawehea ngā taha e rua ki te 15.
x=-\frac{16}{15}
Ka taea te hautanga \frac{-16}{15} te tuhi anō ko -\frac{16}{15} mā te tango i te tohu tōraro.
