Whakaoti mō x
x=\frac{y-5z+15}{3}
Whakaoti mō y
y=3x+5z-15
Tohaina
Kua tāruatia ki te papatopenga
3x+5z=15+y
Me tāpiri te y ki ngā taha e rua.
3x=15+y-5z
Tangohia te 5z mai i ngā taha e rua.
3x=y-5z+15
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{y-5z+15}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{y-5z+15}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
x=\frac{y}{3}-\frac{5z}{3}+5
Whakawehe 15+y-5z ki te 3.
-y+5z=15-3x
Tangohia te 3x mai i ngā taha e rua.
-y=15-3x-5z
Tangohia te 5z mai i ngā taha e rua.
-y=15-5z-3x
He hanga arowhānui tō te whārite.
\frac{-y}{-1}=\frac{15-5z-3x}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{15-5z-3x}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=3x+5z-15
Whakawehe 15-3x-5z ki te -1.
