Whakaoti mō x
x=\frac{3y+2z+6}{5}
Whakaoti mō y
y=\frac{5x}{3}-\frac{2z}{3}-2
Tohaina
Kua tāruatia ki te papatopenga
5x-2z=6+3y
Me tāpiri te 3y ki ngā taha e rua.
5x=6+3y+2z
Me tāpiri te 2z ki ngā taha e rua.
5x=3y+2z+6
He hanga arowhānui tō te whārite.
\frac{5x}{5}=\frac{3y+2z+6}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{3y+2z+6}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
-3y-2z=6-5x
Tangohia te 5x mai i ngā taha e rua.
-3y=6-5x+2z
Me tāpiri te 2z ki ngā taha e rua.
-3y=6+2z-5x
He hanga arowhānui tō te whārite.
\frac{-3y}{-3}=\frac{6+2z-5x}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{6+2z-5x}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{5x}{3}-\frac{2z}{3}-2
Whakawehe 6-5x+2z ki te -3.
