s-4x+8=2-2x
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te x-2.
s+8=2-2x+4x
Me tāpiri te 4x ki ngā taha e rua.
s+8=2+2x
Pahekotia te -2x me 4x, ka 2x.
s=2+2x-8
Tangohia te 8 mai i ngā taha e rua.
s=-6+2x
Tangohia te 8 i te 2, ka -6.
s-4x+8=2-2x
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te x-2.
s-4x+8+2x=2
Me tāpiri te 2x ki ngā taha e rua.
s-2x+8=2
Pahekotia te -4x me 2x, ka -2x.
-2x+8=2-s
Tangohia te s mai i ngā taha e rua.
-2x=2-s-8
Tangohia te 8 mai i ngā taha e rua.
-2x=-6-s
Tangohia te 8 i te 2, ka -6.
-2x=-s-6
He hanga arowhānui tō te whārite.
\frac{-2x}{-2}=\frac{-s-6}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{-s-6}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=\frac{s}{2}+3
Whakawehe -6-s ki te -2.
