Kua tāruatia ki te papatopenga
4x-z+67=-2y
Tangohia te 2y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
4x+67=-2y+z
Me tāpiri te z ki ngā taha e rua.
4x=-2y+z-67
Tangohia te 67 mai i ngā taha e rua.
\frac{4x}{4}=\frac{-2y+z-67}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{-2y+z-67}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=\frac{z}{4}-\frac{y}{2}-\frac{67}{4}
Whakawehe -2y+z-67 ki te 4.
2y-z+67=-4x
Tangohia te 4x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
2y+67=-4x+z
Me tāpiri te z ki ngā taha e rua.
2y=-4x+z-67
Tangohia te 67 mai i ngā taha e rua.
\frac{2y}{2}=\frac{-4x+z-67}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{-4x+z-67}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=\frac{z}{2}-2x-\frac{67}{2}
Whakawehe -4x+z-67 ki te 2.
