Kua tāruatia ki te papatopenga
7y+3=14y-7
Pahekotia te 8y me 6y, ka 14y.
7y+3-14y=-7
Tangohia te 14y mai i ngā taha e rua.
-7y+3=-7
Pahekotia te 7y me -14y, ka -7y.
-7y=-7-3
Tangohia te 3 mai i ngā taha e rua.
-7y=-10
Tangohia te 3 i te -7, ka -10.
y=\frac{-10}{-7}
Whakawehea ngā taha e rua ki te -7.
y=\frac{10}{7}
Ka taea te hautanga \frac{-10}{-7} te whakamāmā ki te \frac{10}{7} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
