Kua tāruatia ki te papatopenga
3x+8z=132-2y
Tangohia te 2y mai i ngā taha e rua.
3x=132-2y-8z
Tangohia te 8z mai i ngā taha e rua.
3x=132-8z-2y
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{132-8z-2y}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{132-8z-2y}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
x=-\frac{2y}{3}-\frac{8z}{3}+44
Whakawehe 132-2y-8z ki te 3.
2y+8z=132-3x
Tangohia te 3x mai i ngā taha e rua.
2y=132-3x-8z
Tangohia te 8z mai i ngā taha e rua.
2y=132-8z-3x
He hanga arowhānui tō te whārite.
\frac{2y}{2}=\frac{132-8z-3x}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{132-8z-3x}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=-\frac{3x}{2}-4z+66
Whakawehe 132-3x-8z ki te 2.
