Kua tāruatia ki te papatopenga
13x-39=26y
Me tāpiri te 26y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
13x=26y+39
Me tāpiri te 39 ki ngā taha e rua.
\frac{13x}{13}=\frac{26y+39}{13}
Whakawehea ngā taha e rua ki te 13.
x=\frac{26y+39}{13}
Mā te whakawehe ki te 13 ka wetekia te whakareanga ki te 13.
x=2y+3
Whakawehe 26y+39 ki te 13.
-26y-39=-13x
Tangohia te 13x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-26y=-13x+39
Me tāpiri te 39 ki ngā taha e rua.
-26y=39-13x
He hanga arowhānui tō te whārite.
\frac{-26y}{-26}=\frac{39-13x}{-26}
Whakawehea ngā taha e rua ki te -26.
y=\frac{39-13x}{-26}
Mā te whakawehe ki te -26 ka wetekia te whakareanga ki te -26.
y=\frac{x-3}{2}
Whakawehe -13x+39 ki te -26.
