Graph
Tohaina
Kua tāruatia ki te papatopenga
5x-12x=-20
Tangohia te 12x mai i ngā taha e rua.
-7x=-20
Pahekotia te 5x me -12x, ka -7x.
x=\frac{-20}{-7}
Whakawehea ngā taha e rua ki te -7.
x=\frac{20}{7}
Ka taea te hautanga \frac{-20}{-7} te whakamāmā ki te \frac{20}{7} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
