Kua tāruatia ki te papatopenga
8x=-7+4y
Me tāpiri te 4y ki ngā taha e rua.
8x=4y-7
He hanga arowhānui tō te whārite.
\frac{8x}{8}=\frac{4y-7}{8}
Whakawehea ngā taha e rua ki te 8.
x=\frac{4y-7}{8}
Mā te whakawehe ki te 8 ka wetekia te whakareanga ki te 8.
x=\frac{y}{2}-\frac{7}{8}
Whakawehe -7+4y ki te 8.
-4y=-7-8x
Tangohia te 8x mai i ngā taha e rua.
-4y=-8x-7
He hanga arowhānui tō te whārite.
\frac{-4y}{-4}=\frac{-8x-7}{-4}
Whakawehea ngā taha e rua ki te -4.
y=\frac{-8x-7}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
y=2x+\frac{7}{4}
Whakawehe -7-8x ki te -4.
