3\left(x-1\right)-4\left(x+2\right)=12
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 4,3.
3x-3-4\left(x+2\right)=12
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-1.
3x-3-4x-8=12
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te x+2.
-x-3-8=12
Pahekotia te 3x me -4x, ka -x.
-x-11=12
Tangohia te 8 i te -3, ka -11.
-x=12+11
Me tāpiri te 11 ki ngā taha e rua.
-x=23
Tāpirihia te 12 ki te 11, ka 23.
x=-23
Me whakarea ngā taha e rua ki te -1.
