x-4+3\left(2x+8\right)=48+2\left(4x-1\right)
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 6,2,3.
x-4+6x+24=48+2\left(4x-1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x+8.
7x-4+24=48+2\left(4x-1\right)
Pahekotia te x me 6x, ka 7x.
7x+20=48+2\left(4x-1\right)
Tāpirihia te -4 ki te 24, ka 20.
7x+20=48+8x-2
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 4x-1.
7x+20=46+8x
Tangohia te 2 i te 48, ka 46.
7x+20-8x=46
Tangohia te 8x mai i ngā taha e rua.
-x+20=46
Pahekotia te 7x me -8x, ka -x.
-x=46-20
Tangohia te 20 mai i ngā taha e rua.
-x=26
Tangohia te 20 i te 46, ka 26.
x=-26
Me whakarea ngā taha e rua ki te -1.
