-12x+48=36-12y
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te -4x+16.
-12x=36-12y-48
Tangohia te 48 mai i ngā taha e rua.
-12x=-12-12y
Tangohia te 48 i te 36, ka -12.
-12x=-12y-12
He hanga arowhānui tō te whārite.
\frac{-12x}{-12}=\frac{-12y-12}{-12}
Whakawehea ngā taha e rua ki te -12.
x=\frac{-12y-12}{-12}
Mā te whakawehe ki te -12 ka wetekia te whakareanga ki te -12.
x=y+1
Whakawehe -12-12y ki te -12.
-12x+48=36-12y
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te -4x+16.
36-12y=-12x+48
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-12y=-12x+48-36
Tangohia te 36 mai i ngā taha e rua.
-12y=-12x+12
Tangohia te 36 i te 48, ka 12.
-12y=12-12x
He hanga arowhānui tō te whārite.
\frac{-12y}{-12}=\frac{12-12x}{-12}
Whakawehea ngā taha e rua ki te -12.
y=\frac{12-12x}{-12}
Mā te whakawehe ki te -12 ka wetekia te whakareanga ki te -12.
y=x-1
Whakawehe 12-12x ki te -12.
