Kua tāruatia ki te papatopenga
-2x-7=-3y
Tangohia te 3y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-2x=-3y+7
Me tāpiri te 7 ki ngā taha e rua.
-2x=7-3y
He hanga arowhānui tō te whārite.
\frac{-2x}{-2}=\frac{7-3y}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{7-3y}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=\frac{3y-7}{2}
Whakawehe -3y+7 ki te -2.
3y-7=2x
Me tāpiri te 2x ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
3y=2x+7
Me tāpiri te 7 ki ngā taha e rua.
\frac{3y}{3}=\frac{2x+7}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{2x+7}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
