Kua tāruatia ki te papatopenga
7y+3=10y-7
Pahekotia te 8y me 2y, ka 10y.
7y+3-10y=-7
Tangohia te 10y mai i ngā taha e rua.
-3y+3=-7
Pahekotia te 7y me -10y, ka -3y.
-3y=-7-3
Tangohia te 3 mai i ngā taha e rua.
-3y=-10
Tangohia te 3 i te -7, ka -10.
y=\frac{-10}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{10}{3}
Ka taea te hautanga \frac{-10}{-3} te whakamāmā ki te \frac{10}{3} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
