4x_{3}-19x_{2}+14x=-x_{4}
Tangohia te x_{4} mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-19x_{2}+14x=-x_{4}-4x_{3}
Tangohia te 4x_{3} mai i ngā taha e rua.
14x=-x_{4}-4x_{3}+19x_{2}
Me tāpiri te 19x_{2} ki ngā taha e rua.
14x=19x_{2}-4x_{3}-x_{4}
He hanga arowhānui tō te whārite.
\frac{14x}{14}=\frac{19x_{2}-4x_{3}-x_{4}}{14}
Whakawehea ngā taha e rua ki te 14.
x=\frac{19x_{2}-4x_{3}-x_{4}}{14}
Mā te whakawehe ki te 14 ka wetekia te whakareanga ki te 14.
x=\frac{19x_{2}}{14}-\frac{x_{4}}{14}-\frac{2x_{3}}{7}
Whakawehe -x_{4}-4x_{3}+19x_{2} ki te 14.
4x_{3}-19x_{2}+14x=-x_{4}
Tangohia te x_{4} mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-19x_{2}+14x=-x_{4}-4x_{3}
Tangohia te 4x_{3} mai i ngā taha e rua.
-19x_{2}=-x_{4}-4x_{3}-14x
Tangohia te 14x mai i ngā taha e rua.
-19x_{2}=-14x-4x_{3}-x_{4}
He hanga arowhānui tō te whārite.
\frac{-19x_{2}}{-19}=\frac{-14x-4x_{3}-x_{4}}{-19}
Whakawehea ngā taha e rua ki te -19.
x_{2}=\frac{-14x-4x_{3}-x_{4}}{-19}
Mā te whakawehe ki te -19 ka wetekia te whakareanga ki te -19.
x_{2}=\frac{14x+4x_{3}+x_{4}}{19}
Whakawehe -x_{4}-4x_{3}-14x ki te -19.
