6-\left(x+3\right)=3x
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 6,2.
6-x-3=3x
Hei kimi i te tauaro o x+3, kimihia te tauaro o ia taurangi.
3-x=3x
Tangohia te 3 i te 6, ka 3.
3-x-3x=0
Tangohia te 3x mai i ngā taha e rua.
3-4x=0
Pahekotia te -x me -3x, ka -4x.
-4x=-3
Tangohia te 3 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-3}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{3}{4}
Ka taea te hautanga \frac{-3}{-4} te whakamāmā ki te \frac{3}{4} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
