Whakaoti mō x
x=\frac{z}{2}-\frac{5y}{4}
Whakaoti mō y
y=\frac{2\left(z-2x\right)}{5}
Tohaina
Kua tāruatia ki te papatopenga
4x-2z=-5y
Tangohia te 5y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
4x=-5y+2z
Me tāpiri te 2z ki ngā taha e rua.
4x=2z-5y
He hanga arowhānui tō te whārite.
\frac{4x}{4}=\frac{2z-5y}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{2z-5y}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=\frac{z}{2}-\frac{5y}{4}
Whakawehe -5y+2z ki te 4.
5y-2z=-4x
Tangohia te 4x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
5y=-4x+2z
Me tāpiri te 2z ki ngā taha e rua.
5y=2z-4x
He hanga arowhānui tō te whārite.
\frac{5y}{5}=\frac{2z-4x}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{2z-4x}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
