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