Kua tāruatia ki te papatopenga
15x-51=8y
Me tāpiri te 8y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
15x=8y+51
Me tāpiri te 51 ki ngā taha e rua.
\frac{15x}{15}=\frac{8y+51}{15}
Whakawehea ngā taha e rua ki te 15.
x=\frac{8y+51}{15}
Mā te whakawehe ki te 15 ka wetekia te whakareanga ki te 15.
x=\frac{8y}{15}+\frac{17}{5}
Whakawehe 8y+51 ki te 15.
-8y-51=-15x
Tangohia te 15x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-8y=-15x+51
Me tāpiri te 51 ki ngā taha e rua.
-8y=51-15x
He hanga arowhānui tō te whārite.
\frac{-8y}{-8}=\frac{51-15x}{-8}
Whakawehea ngā taha e rua ki te -8.
y=\frac{51-15x}{-8}
Mā te whakawehe ki te -8 ka wetekia te whakareanga ki te -8.
y=\frac{15x-51}{8}
Whakawehe -15x+51 ki te -8.
