3\left(3-x\right)-2x=2\left(5x+1\right)-2\left(5x-1\right)
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 4,6.
9-3x-2x=2\left(5x+1\right)-2\left(5x-1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 3-x.
9-5x=2\left(5x+1\right)-2\left(5x-1\right)
Pahekotia te -3x me -2x, ka -5x.
9-5x=10x+2-2\left(5x-1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 5x+1.
9-5x=10x+2-10x+2
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 5x-1.
9-5x=2+2
Pahekotia te 10x me -10x, ka 0.
9-5x=4
Tāpirihia te 2 ki te 2, ka 4.
-5x=4-9
Tangohia te 9 mai i ngā taha e rua.
-5x=-5
Tangohia te 9 i te 4, ka -5.
x=\frac{-5}{-5}
Whakawehea ngā taha e rua ki te -5.
x=1
Whakawehea te -5 ki te -5, kia riro ko 1.
