Kua tāruatia ki te papatopenga
-7x-8=-3y
Tangohia te 3y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-7x=-3y+8
Me tāpiri te 8 ki ngā taha e rua.
-7x=8-3y
He hanga arowhānui tō te whārite.
\frac{-7x}{-7}=\frac{8-3y}{-7}
Whakawehea ngā taha e rua ki te -7.
x=\frac{8-3y}{-7}
Mā te whakawehe ki te -7 ka wetekia te whakareanga ki te -7.
x=\frac{3y-8}{7}
Whakawehe -3y+8 ki te -7.
3y-8=7x
Me tāpiri te 7x ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
3y=7x+8
Me tāpiri te 8 ki ngā taha e rua.
\frac{3y}{3}=\frac{7x+8}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{7x+8}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
