15-5y-125=0
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 3-y.
-110-5y=0
Tangohia te 125 i te 15, ka -110.
-5y=110
Me tāpiri te 110 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
y=\frac{110}{-5}
Whakawehea ngā taha e rua ki te -5.
y=-22
Whakawehea te 110 ki te -5, kia riro ko -22.
