Kua tāruatia ki te papatopenga
1200x=1720000+2500y
Me tāpiri te 2500y ki ngā taha e rua.
1200x=2500y+1720000
He hanga arowhānui tō te whārite.
\frac{1200x}{1200}=\frac{2500y+1720000}{1200}
Whakawehea ngā taha e rua ki te 1200.
x=\frac{2500y+1720000}{1200}
Mā te whakawehe ki te 1200 ka wetekia te whakareanga ki te 1200.
x=\frac{25y}{12}+\frac{4300}{3}
Whakawehe 1720000+2500y ki te 1200.
-2500y=1720000-1200x
Tangohia te 1200x mai i ngā taha e rua.
\frac{-2500y}{-2500}=\frac{1720000-1200x}{-2500}
Whakawehea ngā taha e rua ki te -2500.
y=\frac{1720000-1200x}{-2500}
Mā te whakawehe ki te -2500 ka wetekia te whakareanga ki te -2500.
y=\frac{12x}{25}-688
Whakawehe 1720000-1200x ki te -2500.
