3\left(3x-1\right)-6x=2\left(5-x\right)
Me whakarea ngā taha e rua o te whārite ki te 18, arā, te tauraro pātahi he tino iti rawa te kitea o 6,3,9.
9x-3-6x=2\left(5-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 3x-1.
3x-3=2\left(5-x\right)
Pahekotia te 9x me -6x, ka 3x.
3x-3=10-2x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 5-x.
3x-3+2x=10
Me tāpiri te 2x ki ngā taha e rua.
5x-3=10
Pahekotia te 3x me 2x, ka 5x.
5x=10+3
Me tāpiri te 3 ki ngā taha e rua.
5x=13
Tāpirihia te 10 ki te 3, ka 13.
x=\frac{13}{5}
Whakawehea ngā taha e rua ki te 5.
