2\left(4x+1\right)+x-5=24
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 3,6.
8x+2+x-5=24
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 4x+1.
9x+2-5=24
Pahekotia te 8x me x, ka 9x.
9x-3=24
Tangohia te 5 i te 2, ka -3.
9x=24+3
Me tāpiri te 3 ki ngā taha e rua.
9x=27
Tāpirihia te 24 ki te 3, ka 27.
x=\frac{27}{9}
Whakawehea ngā taha e rua ki te 9.
x=3
Whakawehea te 27 ki te 9, kia riro ko 3.
