-x_{2}+2x_{3}+5x_{4}=-7-377
Subtract 377 from both sides.
-x_{2}+2x_{3}+5x_{4}=-384
Subtract 377 from -7 to get -384.
-x_{2}+5x_{4}=-384-2x_{3}
Subtract 2x_{3} from both sides.
-x_{2}=-384-2x_{3}-5x_{4}
Subtract 5x_{4} from both sides.
-x_{2}=-2x_{3}-5x_{4}-384
The equation is in standard form.
\frac{-x_{2}}{-1}=\frac{-2x_{3}-5x_{4}-384}{-1}
Divide both sides by -1.
x_{2}=\frac{-2x_{3}-5x_{4}-384}{-1}
Dividing by -1 undoes the multiplication by -1.
x_{2}=2x_{3}+5x_{4}+384
Divide -384-2x_{3}-5x_{4} by -1.
-x_{2}+2x_{3}+5x_{4}=-7-377
Subtract 377 from both sides.
-x_{2}+2x_{3}+5x_{4}=-384
Subtract 377 from -7 to get -384.
2x_{3}+5x_{4}=-384+x_{2}
Add x_{2} to both sides.
2x_{3}=-384+x_{2}-5x_{4}
Subtract 5x_{4} from both sides.
2x_{3}=x_{2}-5x_{4}-384
The equation is in standard form.
\frac{2x_{3}}{2}=\frac{x_{2}-5x_{4}-384}{2}
Divide both sides by 2.
x_{3}=\frac{x_{2}-5x_{4}-384}{2}
Dividing by 2 undoes the multiplication by 2.
x_{3}=\frac{x_{2}}{2}-\frac{5x_{4}}{2}-192
Divide -384+x_{2}-5x_{4} by 2.
