Tohaina
Kua tāruatia ki te papatopenga
12y+12x=20y+2z
Whakareatia ngā taha e rua o te whārite ki te 4.
12x=20y+2z-12y
Tangohia te 12y mai i ngā taha e rua.
12x=8y+2z
Pahekotia te 20y me -12y, ka 8y.
\frac{12x}{12}=\frac{8y+2z}{12}
Whakawehea ngā taha e rua ki te 12.
x=\frac{8y+2z}{12}
Mā te whakawehe ki te 12 ka wetekia te whakareanga ki te 12.
x=\frac{z}{6}+\frac{2y}{3}
Whakawehe 8y+2z ki te 12.
12y+12x=20y+2z
Whakareatia ngā taha e rua o te whārite ki te 4.
12y+12x-20y=2z
Tangohia te 20y mai i ngā taha e rua.
-8y+12x=2z
Pahekotia te 12y me -20y, ka -8y.
-8y=2z-12x
Tangohia te 12x mai i ngā taha e rua.
\frac{-8y}{-8}=\frac{2z-12x}{-8}
Whakawehea ngā taha e rua ki te -8.
y=\frac{2z-12x}{-8}
Mā te whakawehe ki te -8 ka wetekia te whakareanga ki te -8.
y=\frac{3x}{2}-\frac{z}{4}
Whakawehe 2z-12x ki te -8.
