Tohaina
Kua tāruatia ki te papatopenga
3x-2z+1=-5y
Tangohia te 5y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
3x+1=-5y+2z
Me tāpiri te 2z ki ngā taha e rua.
3x=-5y+2z-1
Tangohia te 1 mai i ngā taha e rua.
\frac{3x}{3}=\frac{-5y+2z-1}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{-5y+2z-1}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
5y-2z+1=-3x
Tangohia te 3x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
5y+1=-3x+2z
Me tāpiri te 2z ki ngā taha e rua.
5y=-3x+2z-1
Tangohia te 1 mai i ngā taha e rua.
\frac{5y}{5}=\frac{-3x+2z-1}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{-3x+2z-1}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
