Kua tāruatia ki te papatopenga
7x-10=9y
Me tāpiri te 9y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
7x=9y+10
Me tāpiri te 10 ki ngā taha e rua.
\frac{7x}{7}=\frac{9y+10}{7}
Whakawehea ngā taha e rua ki te 7.
x=\frac{9y+10}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
-9y-10=-7x
Tangohia te 7x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-9y=-7x+10
Me tāpiri te 10 ki ngā taha e rua.
-9y=10-7x
He hanga arowhānui tō te whārite.
\frac{-9y}{-9}=\frac{10-7x}{-9}
Whakawehea ngā taha e rua ki te -9.
y=\frac{10-7x}{-9}
Mā te whakawehe ki te -9 ka wetekia te whakareanga ki te -9.
y=\frac{7x-10}{9}
Whakawehe -7x+10 ki te -9.
