9x+2a+3a=4x
Me tāpiri te 3a ki ngā taha e rua.
9x+5a=4x
Pahekotia te 2a me 3a, ka 5a.
5a=4x-9x
Tangohia te 9x mai i ngā taha e rua.
5a=-5x
Pahekotia te 4x me -9x, ka -5x.
\frac{5a}{5}=-\frac{5x}{5}
Whakawehea ngā taha e rua ki te 5.
a=-\frac{5x}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
a=-x
Whakawehe -5x ki te 5.
9x+2a-4x=-3a
Tangohia te 4x mai i ngā taha e rua.
5x+2a=-3a
Pahekotia te 9x me -4x, ka 5x.
5x=-3a-2a
Tangohia te 2a mai i ngā taha e rua.
5x=-5a
Pahekotia te -3a me -2a, ka -5a.
\frac{5x}{5}=-\frac{5a}{5}
Whakawehea ngā taha e rua ki te 5.
x=-\frac{5a}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
x=-a
Whakawehe -5a ki te 5.
