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