Kua tāruatia ki te papatopenga
-3x+7-12=-8x+3
Pahekotia te 2x me -5x, ka -3x.
-3x-5=-8x+3
Tangohia te 12 i te 7, ka -5.
-3x-5+8x=3
Me tāpiri te 8x ki ngā taha e rua.
5x-5=3
Pahekotia te -3x me 8x, ka 5x.
5x=3+5
Me tāpiri te 5 ki ngā taha e rua.
5x=8
Tāpirihia te 3 ki te 5, ka 8.
x=\frac{8}{5}
Whakawehea ngā taha e rua ki te 5.
