Kua tāruatia ki te papatopenga
2-x-\left(-3\right)=6x
Hei kimi i te tauaro o x-3, kimihia te tauaro o ia taurangi.
2-x+3=6x
Ko te tauaro o -3 ko 3.
5-x=6x
Tāpirihia te 2 ki te 3, ka 5.
5-x-6x=0
Tangohia te 6x mai i ngā taha e rua.
5-7x=0
Pahekotia te -x me -6x, ka -7x.
-7x=-5
Tangohia te 5 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-5}{-7}
Whakawehea ngā taha e rua ki te -7.
x=\frac{5}{7}
Ka taea te hautanga \frac{-5}{-7} te whakamāmā ki te \frac{5}{7} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
