4x-12=-3y
Tangohia te 3y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
4x=-3y+12
Me tāpiri te 12 ki ngā taha e rua.
4x=12-3y
He hanga arowhānui tō te whārite.
\frac{4x}{4}=\frac{12-3y}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{12-3y}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=-\frac{3y}{4}+3
Whakawehe -3y+12 ki te 4.
3y-12=-4x
Tangohia te 4x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
3y=-4x+12
Me tāpiri te 12 ki ngā taha e rua.
3y=12-4x
He hanga arowhānui tō te whārite.
\frac{3y}{3}=\frac{12-4x}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{12-4x}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
y=-\frac{4x}{3}+4
Whakawehe -4x+12 ki te 3.
