Kua tāruatia ki te papatopenga
-15x-45=-5y
Tangohia te 5y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-15x=-5y+45
Me tāpiri te 45 ki ngā taha e rua.
-15x=45-5y
He hanga arowhānui tō te whārite.
\frac{-15x}{-15}=\frac{45-5y}{-15}
Whakawehea ngā taha e rua ki te -15.
x=\frac{45-5y}{-15}
Mā te whakawehe ki te -15 ka wetekia te whakareanga ki te -15.
x=\frac{y}{3}-3
Whakawehe -5y+45 ki te -15.
5y-45=15x
Me tāpiri te 15x ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
5y=15x+45
Me tāpiri te 45 ki ngā taha e rua.
\frac{5y}{5}=\frac{15x+45}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{15x+45}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
y=3x+9
Whakawehe 45+15x ki te 5.
