Kua tāruatia ki te papatopenga
wx+4+w=3x
Me tāpiri te w ki ngā taha e rua.
wx+w=3x-4
Tangohia te 4 mai i ngā taha e rua.
\left(x+1\right)w=3x-4
Pahekotia ngā kīanga tau katoa e whai ana i te w.
\frac{\left(x+1\right)w}{x+1}=\frac{3x-4}{x+1}
Whakawehea ngā taha e rua ki te x+1.
w=\frac{3x-4}{x+1}
Mā te whakawehe ki te x+1 ka wetekia te whakareanga ki te x+1.
wx+4-3x=-w
Tangohia te 3x mai i ngā taha e rua.
wx-3x=-w-4
Tangohia te 4 mai i ngā taha e rua.
\left(w-3\right)x=-w-4
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(w-3\right)x}{w-3}=\frac{-w-4}{w-3}
Whakawehea ngā taha e rua ki te w-3.
x=\frac{-w-4}{w-3}
Mā te whakawehe ki te w-3 ka wetekia te whakareanga ki te w-3.
x=-\frac{w+4}{w-3}
Whakawehe -w-4 ki te w-3.
