15x+22000-10x=27000
Whakamahia te āhuatanga tohatoha hei whakarea te 10 ki te 2200-x.
5x+22000=27000
Pahekotia te 15x me -10x, ka 5x.
5x=27000-22000
Tangohia te 22000 mai i ngā taha e rua.
5x=5000
Tangohia te 22000 i te 27000, ka 5000.
x=\frac{5000}{5}
Whakawehea ngā taha e rua ki te 5.
x=1000
Whakawehea te 5000 ki te 5, kia riro ko 1000.
