13x+12x_{12}=65520
Pahekotia te x me 12x, ka 13x.
13x=65520-12x_{12}
Tangohia te 12x_{12} mai i ngā taha e rua.
\frac{13x}{13}=\frac{65520-12x_{12}}{13}
Whakawehea ngā taha e rua ki te 13.
x=\frac{65520-12x_{12}}{13}
Mā te whakawehe ki te 13 ka wetekia te whakareanga ki te 13.
x=-\frac{12x_{12}}{13}+5040
Whakawehe 65520-12x_{12} ki te 13.
13x+12x_{12}=65520
Pahekotia te x me 12x, ka 13x.
12x_{12}=65520-13x
Tangohia te 13x mai i ngā taha e rua.
\frac{12x_{12}}{12}=\frac{65520-13x}{12}
Whakawehea ngā taha e rua ki te 12.
