-4x-4+2x=3\left(2x-1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te x+1.
-2x-4=3\left(2x-1\right)
Pahekotia te -4x me 2x, ka -2x.
-2x-4=6x-3
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x-1.
-2x-4-6x=-3
Tangohia te 6x mai i ngā taha e rua.
-8x-4=-3
Pahekotia te -2x me -6x, ka -8x.
-8x=-3+4
Me tāpiri te 4 ki ngā taha e rua.
-8x=1
Tāpirihia te -3 ki te 4, ka 1.
x=\frac{1}{-8}
Whakawehea ngā taha e rua ki te -8.
x=-\frac{1}{8}
Ka taea te hautanga \frac{1}{-8} te tuhi anō ko -\frac{1}{8} mā te tango i te tohu tōraro.
