-3x-21-9x=13y-5
Tangohia te 9x mai i ngā taha e rua.
-12x-21=13y-5
Pahekotia te -3x me -9x, ka -12x.
-12x=13y-5+21
Me tāpiri te 21 ki ngā taha e rua.
-12x=13y+16
Tāpirihia te -5 ki te 21, ka 16.
\frac{-12x}{-12}=\frac{13y+16}{-12}
Whakawehea ngā taha e rua ki te -12.
x=\frac{13y+16}{-12}
Mā te whakawehe ki te -12 ka wetekia te whakareanga ki te -12.
x=-\frac{13y}{12}-\frac{4}{3}
Whakawehe 13y+16 ki te -12.
13y+9x-5=-3x-21
