Tangohia te 40 i te 500, ka 460.
460+x=2y+20
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te y+10.
x=2y+20-460
Tangohia te 460 mai i ngā taha e rua.
x=2y-440
Tangohia te 460 i te 20, ka -440.
460+x=2\left(y+10\right)
Tangohia te 40 i te 500, ka 460.
460+x=2y+20
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te y+10.
2y+20=460+x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2y=460+x-20
Tangohia te 20 mai i ngā taha e rua.
2y=440+x
Tangohia te 20 i te 460, ka 440.
2y=x+440
He hanga arowhānui tō te whārite.
\frac{2y}{2}=\frac{x+440}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{x+440}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=\frac{x}{2}+220
Whakawehe 440+x ki te 2.
