-x_{2}=-384-2x_{3}-5x_{4}
Tangohia te 5x_{4} mai i ngā taha e rua.
-x_{2}=-2x_{3}-5x_{4}-384
He hanga arowhānui tō te whārite.
\frac{-x_{2}}{-1}=\frac{-2x_{3}-5x_{4}-384}{-1}
Whakawehea ngā taha e rua ki te -1.
x_{2}=\frac{-2x_{3}-5x_{4}-384}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x_{2}=2x_{3}+5x_{4}+384
Whakawehe -384-2x_{3}-5x_{4} ki te -1.
-x_{2}+2x_{3}+5x_{4}=-7-377
