Tohaina
Kua tāruatia ki te papatopenga
x+3z-3x=8
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te z-x.
-2x+3z=8
Pahekotia te x me -3x, ka -2x.
-2x=8-3z
Tangohia te 3z mai i ngā taha e rua.
\frac{-2x}{-2}=\frac{8-3z}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{8-3z}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=\frac{3z}{2}-4
Whakawehe 8-3z ki te -2.
x+3z-3x=8
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te z-x.
-2x+3z=8
Pahekotia te x me -3x, ka -2x.
3z=8+2x
Me tāpiri te 2x ki ngā taha e rua.
3z=2x+8
He hanga arowhānui tō te whārite.
\frac{3z}{3}=\frac{2x+8}{3}
Whakawehea ngā taha e rua ki te 3.
z=\frac{2x+8}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
