\frac{-189}{-7}=4x-1
Whakawehea ngā taha e rua ki te -7.
27=4x-1
Whakawehea te -189 ki te -7, kia riro ko 27.
4x-1=27
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
4x=27+1
Me tāpiri te 1 ki ngā taha e rua.
4x=28
Tāpirihia te 27 ki te 1, ka 28.
x=\frac{28}{4}
Whakawehea ngā taha e rua ki te 4.
x=7
Whakawehea te 28 ki te 4, kia riro ko 7.
