Kua tāruatia ki te papatopenga
6x+15=2y
Me tāpiri te 2y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
6x=2y-15
Tangohia te 15 mai i ngā taha e rua.
\frac{6x}{6}=\frac{2y-15}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{2y-15}{6}
Mā te whakawehe ki te 6 ka wetekia te whakareanga ki te 6.
x=\frac{y}{3}-\frac{5}{2}
Whakawehe 2y-15 ki te 6.
-2y+15=-6x
Tangohia te 6x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-2y=-6x-15
Tangohia te 15 mai i ngā taha e rua.
\frac{-2y}{-2}=\frac{-6x-15}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{-6x-15}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=3x+\frac{15}{2}
Whakawehe -6x-15 ki te -2.
