Kua tāruatia ki te papatopenga
4\left(3-x\right)-6\left(x+1\right)=3\times 5x
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 3,2,4.
12-4x-6\left(x+1\right)=3\times 5x
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 3-x.
12-4x-6x-6=3\times 5x
Whakamahia te āhuatanga tohatoha hei whakarea te -6 ki te x+1.
12-10x-6=3\times 5x
Pahekotia te -4x me -6x, ka -10x.
6-10x=3\times 5x
Tangohia te 6 i te 12, ka 6.
6-10x=15x
Whakareatia te 3 ki te 5, ka 15.
6-10x-15x=0
Tangohia te 15x mai i ngā taha e rua.
6-25x=0
Pahekotia te -10x me -15x, ka -25x.
-25x=-6
Tangohia te 6 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-6}{-25}
Whakawehea ngā taha e rua ki te -25.
x=\frac{6}{25}
Ka taea te hautanga \frac{-6}{-25} te whakamāmā ki te \frac{6}{25} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
