2x-3-\left(-2x\right)+8=6x+2-3\left(-2+3x\right)
Hei kimi i te tauaro o 3-2x, kimihia te tauaro o ia taurangi.
2x-3+2x+8=6x+2-3\left(-2+3x\right)
Ko te tauaro o -2x ko 2x.
4x-3+8=6x+2-3\left(-2+3x\right)
Pahekotia te 2x me 2x, ka 4x.
4x+5=6x+2-3\left(-2+3x\right)
Tāpirihia te -3 ki te 8, ka 5.
4x+5=6x+2+6-9x
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te -2+3x.
4x+5=6x+8-9x
Tāpirihia te 2 ki te 6, ka 8.
4x+5=-3x+8
Pahekotia te 6x me -9x, ka -3x.
4x+5+3x=8
Me tāpiri te 3x ki ngā taha e rua.
7x+5=8
Pahekotia te 4x me 3x, ka 7x.
7x=8-5
Tangohia te 5 mai i ngā taha e rua.
7x=3
Tangohia te 5 i te 8, ka 3.
x=\frac{3}{7}
Whakawehea ngā taha e rua ki te 7.
