Kua tāruatia ki te papatopenga
2\left(3x+1\right)-\left(2\times 6+1\right)=2\left(5x+8\right)
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 3,6.
6x+2-\left(2\times 6+1\right)=2\left(5x+8\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 3x+1.
6x+2-\left(12+1\right)=2\left(5x+8\right)
Whakareatia te 2 ki te 6, ka 12.
6x+2-13=2\left(5x+8\right)
Tāpirihia te 12 ki te 1, ka 13.
6x-11=2\left(5x+8\right)
Tangohia te 13 i te 2, ka -11.
6x-11=10x+16
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 5x+8.
6x-11-10x=16
Tangohia te 10x mai i ngā taha e rua.
-4x-11=16
Pahekotia te 6x me -10x, ka -4x.
-4x=16+11
Me tāpiri te 11 ki ngā taha e rua.
-4x=27
Tāpirihia te 16 ki te 11, ka 27.
x=\frac{27}{-4}
Whakawehea ngā taha e rua ki te -4.
x=-\frac{27}{4}
Ka taea te hautanga \frac{27}{-4} te tuhi anō ko -\frac{27}{4} mā te tango i te tohu tōraro.
