Kua tāruatia ki te papatopenga
10x-81=3y
Me tāpiri te 3y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
10x=3y+81
Me tāpiri te 81 ki ngā taha e rua.
\frac{10x}{10}=\frac{3y+81}{10}
Whakawehea ngā taha e rua ki te 10.
x=\frac{3y+81}{10}
Mā te whakawehe ki te 10 ka wetekia te whakareanga ki te 10.
-3y-81=-10x
Tangohia te 10x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-3y=-10x+81
Me tāpiri te 81 ki ngā taha e rua.
-3y=81-10x
He hanga arowhānui tō te whārite.
\frac{-3y}{-3}=\frac{81-10x}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{81-10x}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{10x}{3}-27
Whakawehe -10x+81 ki te -3.
