Linear Equation
x-2=8x-16
Tohaina
Kua tāruatia ki te papatopenga
x-2-8x=-16
Tangohia te 8x mai i ngā taha e rua.
-7x-2=-16
Pahekotia te x me -8x, ka -7x.
-7x=-16+2
Me tāpiri te 2 ki ngā taha e rua.
-7x=-14
Tāpirihia te -16 ki te 2, ka -14.
x=\frac{-14}{-7}
Whakawehea ngā taha e rua ki te -7.
x=2
Whakawehea te -14 ki te -7, kia riro ko 2.
