6y+6=-24-9y
Pahekotia te 11y me -5y, ka 6y.
6y+6+9y=-24
Me tāpiri te 9y ki ngā taha e rua.
15y+6=-24
Pahekotia te 6y me 9y, ka 15y.
15y=-24-6
Tangohia te 6 mai i ngā taha e rua.
15y=-30
Tangohia te 6 i te -24, ka -30.
y=\frac{-30}{15}
Whakawehea ngā taha e rua ki te 15.
y=-2
Whakawehea te -30 ki te 15, kia riro ko -2.
