y-2=-195+5y-3
Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te 39-y.
y-2=-198+5y
Tangohia te 3 i te -195, ka -198.
y-2-5y=-198
Tangohia te 5y mai i ngā taha e rua.
-4y-2=-198
Pahekotia te y me -5y, ka -4y.
-4y=-198+2
Me tāpiri te 2 ki ngā taha e rua.
-4y=-196
Tāpirihia te -198 ki te 2, ka -196.
y=\frac{-196}{-4}
Whakawehea ngā taha e rua ki te -4.
y=49
Whakawehea te -196 ki te -4, kia riro ko 49.
