4\left(3x-2\right)-2\left(4x-3\right)=3x+1
Me whakarea ngā taha e rua o te whārite ki te 8, arā, te tauraro pātahi he tino iti rawa te kitea o 2,4,8.
12x-8-2\left(4x-3\right)=3x+1
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 3x-2.
12x-8-8x+6=3x+1
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 4x-3.
4x-8+6=3x+1
Pahekotia te 12x me -8x, ka 4x.
4x-2=3x+1
Tāpirihia te -8 ki te 6, ka -2.
4x-2-3x=1
Tangohia te 3x mai i ngā taha e rua.
x-2=1
Pahekotia te 4x me -3x, ka x.
x=1+2
Me tāpiri te 2 ki ngā taha e rua.
x=3
Tāpirihia te 1 ki te 2, ka 3.
