9-10x=15x
Pahekotia te 7x me 8x, ka 15x.
9-10x-15x=0
Tangohia te 15x mai i ngā taha e rua.
9-25x=0
Pahekotia te -10x me -15x, ka -25x.
-25x=-9
Tangohia te 9 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-9}{-25}
Whakawehea ngā taha e rua ki te -25.
x=\frac{9}{25}
Ka taea te hautanga \frac{-9}{-25} te whakamāmā ki te \frac{9}{25} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
