-6-x=4x-12-7\left(x-4\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x-3.
-6-x=4x-12-7x+28
Whakamahia te āhuatanga tohatoha hei whakarea te -7 ki te x-4.
-6-x=-3x-12+28
Pahekotia te 4x me -7x, ka -3x.
-6-x=-3x+16
Tāpirihia te -12 ki te 28, ka 16.
-6-x+3x=16
Me tāpiri te 3x ki ngā taha e rua.
-6+2x=16
Pahekotia te -x me 3x, ka 2x.
2x=16+6
Me tāpiri te 6 ki ngā taha e rua.
2x=22
Tāpirihia te 16 ki te 6, ka 22.
x=\frac{22}{2}
Whakawehea ngā taha e rua ki te 2.
x=11
Whakawehea te 22 ki te 2, kia riro ko 11.
