Kua tāruatia ki te papatopenga
6x-5+15+y=180
Pahekotia te 2x me 4x, ka 6x.
6x+10+y=180
Tāpirihia te -5 ki te 15, ka 10.
6x+y=180-10
Tangohia te 10 mai i ngā taha e rua.
6x+y=170
Tangohia te 10 i te 180, ka 170.
6x=170-y
Tangohia te y mai i ngā taha e rua.
\frac{6x}{6}=\frac{170-y}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{170-y}{6}
Mā te whakawehe ki te 6 ka wetekia te whakareanga ki te 6.
x=-\frac{y}{6}+\frac{85}{3}
Whakawehe 170-y ki te 6.
6x-5+15+y=180
Pahekotia te 2x me 4x, ka 6x.
6x+10+y=180
Tāpirihia te -5 ki te 15, ka 10.
10+y=180-6x
Tangohia te 6x mai i ngā taha e rua.
y=180-6x-10
Tangohia te 10 mai i ngā taha e rua.
y=170-6x
