2\left(x+1\right)-2\left(3x-1\right)=2\left(2x+1\right)
Me whakarea ngā taha e rua o te whārite ki te 4, arā, te tauraro pātahi he tino iti rawa te kitea o 2,4.
2x+2-2\left(3x-1\right)=2\left(2x+1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+1.
2x+2-6x+2=2\left(2x+1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 3x-1.
-4x+2+2=2\left(2x+1\right)
Pahekotia te 2x me -6x, ka -4x.
-4x+4=2\left(2x+1\right)
Tāpirihia te 2 ki te 2, ka 4.
-4x+4=4x+2
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2x+1.
-4x+4-4x=2
Tangohia te 4x mai i ngā taha e rua.
-8x+4=2
Pahekotia te -4x me -4x, ka -8x.
-8x=2-4
Tangohia te 4 mai i ngā taha e rua.
-8x=-2
Tangohia te 4 i te 2, ka -2.
x=\frac{-2}{-8}
Whakawehea ngā taha e rua ki te -8.
x=\frac{1}{4}
Whakahekea te hautanga \frac{-2}{-8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.
