-12x-12+2x=-82
Whakamahia te āhuatanga tohatoha hei whakarea te -6 ki te 2x+2.
-10x-12=-82
Pahekotia te -12x me 2x, ka -10x.
-10x=-82+12
Me tāpiri te 12 ki ngā taha e rua.
-10x=-70
Tāpirihia te -82 ki te 12, ka -70.
x=\frac{-70}{-10}
Whakawehea ngā taha e rua ki te -10.
x=7
Whakawehea te -70 ki te -10, kia riro ko 7.
