Kua tāruatia ki te papatopenga
x-55y=4950
Whakareatia te -1 ki te 55, ka -55.
-55y=4950-x
Tangohia te x mai i ngā taha e rua.
\frac{-55y}{-55}=\frac{4950-x}{-55}
Whakawehea ngā taha e rua ki te -55.
y=\frac{4950-x}{-55}
Mā te whakawehe ki te -55 ka wetekia te whakareanga ki te -55.
y=\frac{x}{55}-90
Whakawehe 4950-x ki te -55.
x=4950+y\times 55
Me tāpiri te y\times 55 ki ngā taha e rua.
