Kua tāruatia ki te papatopenga
x-5-12-\left(-2x\right)=0
Hei kimi i te tauaro o 12-2x, kimihia te tauaro o ia taurangi.
x-5-12+2x=0
Ko te tauaro o -2x ko 2x.
x-17+2x=0
Tangohia te 12 i te -5, ka -17.
3x-17=0
Pahekotia te x me 2x, ka 3x.
3x=17
Me tāpiri te 17 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{17}{3}
Whakawehea ngā taha e rua ki te 3.
