-6x+12=-2x+44
Whakamahia te āhuatanga tohatoha hei whakarea te -6 ki te x-2.
-6x+12+2x=44
Me tāpiri te 2x ki ngā taha e rua.
-4x+12=44
Pahekotia te -6x me 2x, ka -4x.
-4x=44-12
Tangohia te 12 mai i ngā taha e rua.
-4x=32
Tangohia te 12 i te 44, ka 32.
x=\frac{32}{-4}
Whakawehea ngā taha e rua ki te -4.
x=-8
Whakawehea te 32 ki te -4, kia riro ko -8.
