2x+36x-63=7+9+8x-2
Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te 4x-7.
38x-63=7+9+8x-2
Pahekotia te 2x me 36x, ka 38x.
38x-63=16+8x-2
Tāpirihia te 7 ki te 9, ka 16.
38x-63=14+8x
Tangohia te 2 i te 16, ka 14.
38x-63-8x=14
Tangohia te 8x mai i ngā taha e rua.
30x-63=14
Pahekotia te 38x me -8x, ka 30x.
30x=14+63
Me tāpiri te 63 ki ngā taha e rua.
30x=77
Tāpirihia te 14 ki te 63, ka 77.
x=\frac{77}{30}
Whakawehea ngā taha e rua ki te 30.
