2x-2a+2b=3x+a
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-a.
2x-2a+2b-a=3x
Tangohia te a mai i ngā taha e rua.
2x-3a+2b=3x
Pahekotia te -2a me -a, ka -3a.
-3a+2b=3x-2x
Tangohia te 2x mai i ngā taha e rua.
-3a+2b=x
Pahekotia te 3x me -2x, ka x.
-3a=x-2b
Tangohia te 2b mai i ngā taha e rua.
\frac{-3a}{-3}=\frac{x-2b}{-3}
Whakawehea ngā taha e rua ki te -3.
a=\frac{x-2b}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
a=\frac{2b-x}{3}
Whakawehe x-2b ki te -3.
2x-2a+2b=3x+a
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-a.
-2a+2b=3x+a-2x
Tangohia te 2x mai i ngā taha e rua.
-2a+2b=x+a
Pahekotia te 3x me -2x, ka x.
2b=x+a+2a
Me tāpiri te 2a ki ngā taha e rua.
2b=x+3a
Pahekotia te a me 2a, ka 3a.
\frac{2b}{2}=\frac{x+3a}{2}
Whakawehea ngā taha e rua ki te 2.
b=\frac{x+3a}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
