3\left(2x-1\right)+3\left(x+2\right)=2\left(2x+7\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.
6x-3+3\left(x+2\right)=2\left(2x+7\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x-1.
6x-3+3x+6=2\left(2x+7\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+2.
9x-3+6=2\left(2x+7\right)
Pahekotia te 6x me 3x, ka 9x.
9x+3=2\left(2x+7\right)
Tāpirihia te -3 ki te 6, ka 3.
9x+3=4x+14
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2x+7.
9x+3-4x=14
Tangohia te 4x mai i ngā taha e rua.
5x+3=14
Pahekotia te 9x me -4x, ka 5x.
5x=14-3
Tangohia te 3 mai i ngā taha e rua.
5x=11
Tangohia te 3 i te 14, ka 11.
x=\frac{11}{5}
Whakawehea ngā taha e rua ki te 5.
