Tohaina
Kua tāruatia ki te papatopenga
-4y=10-x_{2}
Tangohia te x_{2} mai i ngā taha e rua.
\frac{-4y}{-4}=\frac{10-x_{2}}{-4}
Whakawehea ngā taha e rua ki te -4.
y=\frac{10-x_{2}}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
y=\frac{x_{2}}{4}-\frac{5}{2}
Whakawehe 10-x_{2} ki te -4.
x_{2}=10+4y
Me tāpiri te 4y ki ngā taha e rua.
