-14y-77-2y=-13
Whakamahia te āhuatanga tohatoha hei whakarea te -7 ki te 2y+11.
-16y-77=-13
Pahekotia te -14y me -2y, ka -16y.
-16y=-13+77
Me tāpiri te 77 ki ngā taha e rua.
-16y=64
Tāpirihia te -13 ki te 77, ka 64.
y=\frac{64}{-16}
Whakawehea ngā taha e rua ki te -16.
y=-4
Whakawehea te 64 ki te -16, kia riro ko -4.
