Kua tāruatia ki te papatopenga
x+2x-3z-2-z=-3
Ko te tauaro o -2x ko 2x.
3x-3z-2-z=-3
Pahekotia te x me 2x, ka 3x.
3x-4z-2=-3
Pahekotia te -3z me -z, ka -4z.
3x-2=-3+4z
Me tāpiri te 4z ki ngā taha e rua.
3x=-3+4z+2
Me tāpiri te 2 ki ngā taha e rua.
3x=-1+4z
Tāpirihia te -3 ki te 2, ka -1.
3x=4z-1
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{4z-1}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{4z-1}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
x+2x-3z-2-z=-3
Ko te tauaro o -2x ko 2x.
3x-3z-2-z=-3
Pahekotia te x me 2x, ka 3x.
3x-4z-2=-3
Pahekotia te -3z me -z, ka -4z.
-4z-2=-3-3x
Tangohia te 3x mai i ngā taha e rua.
-4z=-3-3x+2
Me tāpiri te 2 ki ngā taha e rua.
-4z=-1-3x
Tāpirihia te -3 ki te 2, ka -1.
-4z=-3x-1
He hanga arowhānui tō te whārite.
\frac{-4z}{-4}=\frac{-3x-1}{-4}
Whakawehea ngā taha e rua ki te -4.
z=\frac{-3x-1}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
z=\frac{3x+1}{4}
Whakawehe -1-3x ki te -4.
