Whakaoti mō x
x=\frac{3y}{4}-\frac{11z}{2}
Whakaoti mō y
y=\frac{4x+22z}{3}
Tohaina
Kua tāruatia ki te papatopenga
4x+22z=3y
Me tāpiri te 3y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
4x=3y-22z
Tangohia te 22z mai i ngā taha e rua.
\frac{4x}{4}=\frac{3y-22z}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{3y-22z}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=\frac{3y}{4}-\frac{11z}{2}
Whakawehe 3y-22z ki te 4.
-3y+22z=-4x
Tangohia te 4x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-3y=-4x-22z
Tangohia te 22z mai i ngā taha e rua.
\frac{-3y}{-3}=\frac{-4x-22z}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{-4x-22z}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{4x+22z}{3}
Whakawehe -4x-22z ki te -3.
