3\left(3x-1\right)=2\left(2x+6\right)
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3.
9x-3=2\left(2x+6\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 3x-1.
9x-3=4x+12
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2x+6.
9x-3-4x=12
Tangohia te 4x mai i ngā taha e rua.
5x-3=12
Pahekotia te 9x me -4x, ka 5x.
5x=12+3
Me tāpiri te 3 ki ngā taha e rua.
5x=15
Tāpirihia te 12 ki te 3, ka 15.
x=\frac{15}{5}
Whakawehea ngā taha e rua ki te 5.
x=3
Whakawehea te 15 ki te 5, kia riro ko 3.
