Kua tāruatia ki te papatopenga
3x-7=-4y
Tangohia te 4y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
3x=-4y+7
Me tāpiri te 7 ki ngā taha e rua.
3x=7-4y
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{7-4y}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{7-4y}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
4y-7=-3x
Tangohia te 3x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
4y=-3x+7
Me tāpiri te 7 ki ngā taha e rua.
4y=7-3x
He hanga arowhānui tō te whārite.
\frac{4y}{4}=\frac{7-3x}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{7-3x}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
