13=-6x-17
Pahekotia te -4.8x me -1.2x, ka -6x.
-6x-17=13
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-6x=13+17
Me tāpiri te 17 ki ngā taha e rua.
-6x=30
Tāpirihia te 13 ki te 17, ka 30.
x=\frac{30}{-6}
Whakawehea ngā taha e rua ki te -6.
x=-5
Whakawehea te 30 ki te -6, kia riro ko -5.
