75.65+0.5x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
0.5x=y-75.65
Tangohia te 75.65 mai i ngā taha e rua.
\frac{0.5x}{0.5}=\frac{y-75.65}{0.5}
Me whakarea ngā taha e rua ki te 2.
x=\frac{y-75.65}{0.5}
Mā te whakawehe ki te 0.5 ka wetekia te whakareanga ki te 0.5.
x=2y-151.3
Whakawehe y-75.65 ki te 0.5 mā te whakarea y-75.65 ki te tau huripoki o 0.5.
