Kua tāruatia ki te papatopenga
18+2x+15x=-60
Me tāpiri te 15x ki ngā taha e rua.
18+17x=-60
Pahekotia te 2x me 15x, ka 17x.
17x=-60-18
Tangohia te 18 mai i ngā taha e rua.
17x=-78
Tangohia te 18 i te -60, ka -78.
x=\frac{-78}{17}
Whakawehea ngā taha e rua ki te 17.
x=-\frac{78}{17}
Ka taea te hautanga \frac{-78}{17} te tuhi anō ko -\frac{78}{17} mā te tango i te tohu tōraro.
