-13x-13=17-8x
Pahekotia te 20x me -33x, ka -13x.
-13x-13+8x=17
Me tāpiri te 8x ki ngā taha e rua.
-5x-13=17
Pahekotia te -13x me 8x, ka -5x.
-5x=17+13
Me tāpiri te 13 ki ngā taha e rua.
-5x=30
Tāpirihia te 17 ki te 13, ka 30.
x=\frac{30}{-5}
Whakawehea ngā taha e rua ki te -5.
x=-6
Whakawehea te 30 ki te -5, kia riro ko -6.
