9x-2x-16=5x-11
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x+8.
7x-16=5x-11
Pahekotia te 9x me -2x, ka 7x.
7x-16-5x=-11
Tangohia te 5x mai i ngā taha e rua.
2x-16=-11
Pahekotia te 7x me -5x, ka 2x.
2x=-11+16
Me tāpiri te 16 ki ngā taha e rua.
2x=5
Tāpirihia te -11 ki te 16, ka 5.
x=\frac{5}{2}
Whakawehea ngā taha e rua ki te 2.
