3\left(5x+6\right)=2\left(9x-3\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.
15x+18=2\left(9x-3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 5x+6.
15x+18=18x-6
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 9x-3.
15x+18-18x=-6
Tangohia te 18x mai i ngā taha e rua.
-3x+18=-6
Pahekotia te 15x me -18x, ka -3x.
-3x=-6-18
Tangohia te 18 mai i ngā taha e rua.
-3x=-24
Tangohia te 18 i te -6, ka -24.
x=\frac{-24}{-3}
Whakawehea ngā taha e rua ki te -3.
x=8
Whakawehea te -24 ki te -3, kia riro ko 8.
