6x+225-15x=140
Whakamahia te āhuatanga tohatoha hei whakarea te 15 ki te 15-x.
-9x+225=140
Pahekotia te 6x me -15x, ka -9x.
-9x=140-225
Tangohia te 225 mai i ngā taha e rua.
-9x=-85
Tangohia te 225 i te 140, ka -85.
x=\frac{-85}{-9}
Whakawehea ngā taha e rua ki te -9.
x=\frac{85}{9}
Ka taea te hautanga \frac{-85}{-9} te whakamāmā ki te \frac{85}{9} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
