74x-6y=520-74
Tangohia te 74 mai i ngā taha e rua.
74x-6y=446
Tangohia te 74 i te 520, ka 446.
74x=446+6y
Me tāpiri te 6y ki ngā taha e rua.
74x=6y+446
He hanga arowhānui tō te whārite.
\frac{74x}{74}=\frac{6y+446}{74}
Whakawehea ngā taha e rua ki te 74.
x=\frac{6y+446}{74}
Mā te whakawehe ki te 74 ka wetekia te whakareanga ki te 74.
x=\frac{3y+223}{37}
Whakawehe 446+6y ki te 74.
74-6y=520-74x
Tangohia te 74x mai i ngā taha e rua.
-6y=520-74x-74
Tangohia te 74 mai i ngā taha e rua.
-6y=446-74x
Tangohia te 74 i te 520, ka 446.
\frac{-6y}{-6}=\frac{446-74x}{-6}
Whakawehea ngā taha e rua ki te -6.
y=\frac{446-74x}{-6}
Mā te whakawehe ki te -6 ka wetekia te whakareanga ki te -6.
y=\frac{37x-223}{3}
Whakawehe 446-74x ki te -6.
