2x-300=5\left(3y+50\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-150.
2x-300=15y+250
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 3y+50.
2x=15y+250+300
Me tāpiri te 300 ki ngā taha e rua.
2x=15y+550
Tāpirihia te 250 ki te 300, ka 550.
\frac{2x}{2}=\frac{15y+550}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{15y+550}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=\frac{15y}{2}+275
Whakawehe 15y+550 ki te 2.
2x-300=5\left(3y+50\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-150.
2x-300=15y+250
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 3y+50.
15y+250=2x-300
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
15y=2x-300-250
Tangohia te 250 mai i ngā taha e rua.
15y=2x-550
Tangohia te 250 i te -300, ka -550.
\frac{15y}{15}=\frac{2x-550}{15}
Whakawehea ngā taha e rua ki te 15.
y=\frac{2x-550}{15}
Mā te whakawehe ki te 15 ka wetekia te whakareanga ki te 15.
y=\frac{2x}{15}-\frac{110}{3}
Whakawehe -550+2x ki te 15.
