-Cx=70+4x-6x
Tangohia te 6x mai i ngā taha e rua.
-Cx=70-2x
Pahekotia te 4x me -6x, ka -2x.
\left(-x\right)C=70-2x
He hanga arowhānui tō te whārite.
\frac{\left(-x\right)C}{-x}=\frac{70-2x}{-x}
Whakawehea ngā taha e rua ki te -x.
C=\frac{70-2x}{-x}
Mā te whakawehe ki te -x ka wetekia te whakareanga ki te -x.
C=2-\frac{70}{x}
Whakawehe 70-2x ki te -x.
6x-Cx-4x=70
Tangohia te 4x mai i ngā taha e rua.
2x-Cx=70
Pahekotia te 6x me -4x, ka 2x.
\left(2-C\right)x=70
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(2-C\right)x}{2-C}=\frac{70}{2-C}
Whakawehea ngā taha e rua ki te 2-C.
x=\frac{70}{2-C}
Mā te whakawehe ki te 2-C ka wetekia te whakareanga ki te 2-C.
