12x-42y+3z-5x=-9y+32z
Tangohia te 5x mai i ngā taha e rua.
7x-42y+3z=-9y+32z
Pahekotia te 12x me -5x, ka 7x.
7x+3z=-9y+32z+42y
Me tāpiri te 42y ki ngā taha e rua.
7x+3z=33y+32z
Pahekotia te -9y me 42y, ka 33y.
7x=33y+32z-3z
Tangohia te 3z mai i ngā taha e rua.
7x=33y+29z
Pahekotia te 32z me -3z, ka 29z.
\frac{7x}{7}=\frac{33y+29z}{7}
Whakawehea ngā taha e rua ki te 7.
x=\frac{33y+29z}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
12x-42y+3z+9y=5x+32z
Me tāpiri te 9y ki ngā taha e rua.
12x-33y+3z=5x+32z
Pahekotia te -42y me 9y, ka -33y.
-33y+3z=5x+32z-12x
Tangohia te 12x mai i ngā taha e rua.
-33y+3z=-7x+32z
Pahekotia te 5x me -12x, ka -7x.
-33y=-7x+32z-3z
Tangohia te 3z mai i ngā taha e rua.
-33y=-7x+29z
Pahekotia te 32z me -3z, ka 29z.
-33y=29z-7x
He hanga arowhānui tō te whārite.
\frac{-33y}{-33}=\frac{29z-7x}{-33}
Whakawehea ngā taha e rua ki te -33.
y=\frac{29z-7x}{-33}
Mā te whakawehe ki te -33 ka wetekia te whakareanga ki te -33.
y=\frac{7x-29z}{33}
Whakawehe -7x+29z ki te -33.
