Whakaoti mō x
x=-\frac{z}{3}+60
Whakaoti mō z

Tohaina
Kua tāruatia ki te papatopenga
3x+z=180
Pahekotia te 2x me x, ka 3x.
3x=180-z
Tangohia te z mai i ngā taha e rua.
\frac{3x}{3}=\frac{180-z}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{180-z}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
x=-\frac{z}{3}+60
Whakawehe 180-z ki te 3.
3x+z=180
Pahekotia te 2x me x, ka 3x.
z=180-3x
Tangohia te 3x mai i ngā taha e rua.
