Tohaina
Kua tāruatia ki te papatopenga
4y-9x=3-7z
Tangohia te 7z mai i ngā taha e rua.
-9x=3-7z-4y
Tangohia te 4y mai i ngā taha e rua.
\frac{-9x}{-9}=\frac{3-7z-4y}{-9}
Whakawehea ngā taha e rua ki te -9.
x=\frac{3-7z-4y}{-9}
Mā te whakawehe ki te -9 ka wetekia te whakareanga ki te -9.
x=\frac{4y}{9}+\frac{7z}{9}-\frac{1}{3}
Whakawehe 3-7z-4y ki te -9.
4y-9x=3-7z
Tangohia te 7z mai i ngā taha e rua.
4y=3-7z+9x
Me tāpiri te 9x ki ngā taha e rua.
4y=9x-7z+3
He hanga arowhānui tō te whārite.
\frac{4y}{4}=\frac{9x-7z+3}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{9x-7z+3}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
