8x-6-5=6\left(3x-2\right)-2\left(x+1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 4x-3.
8x-11=6\left(3x-2\right)-2\left(x+1\right)
Tangohia te 5 i te -6, ka -11.
8x-11=18x-12-2\left(x+1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te 3x-2.
8x-11=18x-12-2x-2
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x+1.
8x-11=16x-12-2
Pahekotia te 18x me -2x, ka 16x.
8x-11=16x-14
Tangohia te 2 i te -12, ka -14.
8x-11-16x=-14
Tangohia te 16x mai i ngā taha e rua.
-8x-11=-14
Pahekotia te 8x me -16x, ka -8x.
-8x=-14+11
Me tāpiri te 11 ki ngā taha e rua.
-8x=-3
Tāpirihia te -14 ki te 11, ka -3.
x=\frac{-3}{-8}
Whakawehea ngā taha e rua ki te -8.
x=\frac{3}{8}
Ka taea te hautanga \frac{-3}{-8} te whakamāmā ki te \frac{3}{8} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
