Kua tāruatia ki te papatopenga
3x-19=-y
Tangohia te 1y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
3x=-y+19
Me tāpiri te 19 ki ngā taha e rua.
3x=19-y
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{19-y}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{19-y}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
1y-19=-3x
Tangohia te 3x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
1y=-3x+19
Me tāpiri te 19 ki ngā taha e rua.
y=-3x+19
Whakaraupapatia anō ngā kīanga tau.
