Kua tāruatia ki te papatopenga
-12x+56=16y
Me tāpiri te 16y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
-12x=16y-56
Tangohia te 56 mai i ngā taha e rua.
\frac{-12x}{-12}=\frac{16y-56}{-12}
Whakawehea ngā taha e rua ki te -12.
x=\frac{16y-56}{-12}
Mā te whakawehe ki te -12 ka wetekia te whakareanga ki te -12.
x=\frac{14-4y}{3}
Whakawehe 16y-56 ki te -12.
-16y+56=12x
Me tāpiri te 12x ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
-16y=12x-56
Tangohia te 56 mai i ngā taha e rua.
\frac{-16y}{-16}=\frac{12x-56}{-16}
Whakawehea ngā taha e rua ki te -16.
y=\frac{12x-56}{-16}
Mā te whakawehe ki te -16 ka wetekia te whakareanga ki te -16.
y=-\frac{3x}{4}+\frac{7}{2}
Whakawehe 12x-56 ki te -16.
