33600-420x=168\left(x-10\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 420 ki te 80-x.
33600-420x=168x-1680
Whakamahia te āhuatanga tohatoha hei whakarea te 168 ki te x-10.
33600-420x-168x=-1680
Tangohia te 168x mai i ngā taha e rua.
33600-588x=-1680
Pahekotia te -420x me -168x, ka -588x.
-588x=-1680-33600
Tangohia te 33600 mai i ngā taha e rua.
-588x=-35280
Tangohia te 33600 i te -1680, ka -35280.
x=\frac{-35280}{-588}
Whakawehea ngā taha e rua ki te -588.
x=60
Whakawehea te -35280 ki te -588, kia riro ko 60.
