Kua tāruatia ki te papatopenga
-2D-4y=3-7c
Tangohia te 7c mai i ngā taha e rua.
-2D=3-7c+4y
Me tāpiri te 4y ki ngā taha e rua.
-2D=4y-7c+3
He hanga arowhānui tō te whārite.
\frac{-2D}{-2}=\frac{4y-7c+3}{-2}
Whakawehea ngā taha e rua ki te -2.
D=\frac{4y-7c+3}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
D=\frac{7c}{2}-2y-\frac{3}{2}
Whakawehe 3-7c+4y ki te -2.
7c-4y=3+2D
Me tāpiri te 2D ki ngā taha e rua.
7c=3+2D+4y
Me tāpiri te 4y ki ngā taha e rua.
7c=4y+2D+3
He hanga arowhānui tō te whārite.
\frac{7c}{7}=\frac{4y+2D+3}{7}
Whakawehea ngā taha e rua ki te 7.
c=\frac{4y+2D+3}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
