Kua tāruatia ki te papatopenga
x=8x-5136+19
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te x-642.
x=8x-5117
Tāpirihia te -5136 ki te 19, ka -5117.
x-8x=-5117
Tangohia te 8x mai i ngā taha e rua.
-7x=-5117
Pahekotia te x me -8x, ka -7x.
x=\frac{-5117}{-7}
Whakawehea ngā taha e rua ki te -7.
x=731
Whakawehea te -5117 ki te -7, kia riro ko 731.
