3\left(2x-5\right)-\left(1+x\right)=6
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,6.
6x-15-\left(1+x\right)=6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x-5.
6x-15-1-x=6
Hei kimi i te tauaro o 1+x, kimihia te tauaro o ia taurangi.
6x-16-x=6
Tangohia te 1 i te -15, ka -16.
5x-16=6
Pahekotia te 6x me -x, ka 5x.
5x=6+16
Me tāpiri te 16 ki ngā taha e rua.
5x=22
Tāpirihia te 6 ki te 16, ka 22.
x=\frac{22}{5}
Whakawehea ngā taha e rua ki te 5.
