Kua tāruatia ki te papatopenga
y+5=-2x-6
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x+3.
-2x-6=y+5
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-2x=y+5+6
Me tāpiri te 6 ki ngā taha e rua.
-2x=y+11
Tāpirihia te 5 ki te 6, ka 11.
\frac{-2x}{-2}=\frac{y+11}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{y+11}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=\frac{-y-11}{2}
Whakawehe y+11 ki te -2.
y+5=-2x-6
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x+3.
y=-2x-6-5
Tangohia te 5 mai i ngā taha e rua.
y=-2x-11
Tangohia te 5 i te -6, ka -11.
