20x-6-5=x+11+4x
Pahekotia te 17x me 3x, ka 20x.
20x-11=x+11+4x
Tangohia te 5 i te -6, ka -11.
20x-11=5x+11
Pahekotia te x me 4x, ka 5x.
20x-11-5x=11
Tangohia te 5x mai i ngā taha e rua.
15x-11=11
Pahekotia te 20x me -5x, ka 15x.
15x=11+11
Me tāpiri te 11 ki ngā taha e rua.
15x=22
Tāpirihia te 11 ki te 11, ka 22.
x=\frac{22}{15}
Whakawehea ngā taha e rua ki te 15.
