4x-5y-12x=0
Tangohia te 12x mai i ngā taha e rua.
-8x-5y=0
Pahekotia te 4x me -12x, ka -8x.
-8x=5y
Me tāpiri te 5y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
\frac{-8x}{-8}=\frac{5y}{-8}
Whakawehea ngā taha e rua ki te -8.
x=\frac{5y}{-8}
Mā te whakawehe ki te -8 ka wetekia te whakareanga ki te -8.
x=-\frac{5y}{8}
Whakawehe 5y ki te -8.
-5y=12x-4x
Tangohia te 4x mai i ngā taha e rua.
-5y=8x
Pahekotia te 12x me -4x, ka 8x.
\frac{-5y}{-5}=\frac{8x}{-5}
Whakawehea ngā taha e rua ki te -5.
y=\frac{8x}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
y=-\frac{8x}{5}
Whakawehe 8x ki te -5.
