Work: Find the solution of equation -393.5*x-483.6*(0.2-x) = -63.53 .
Question type: Equation
Solution:Original question:
| - | 787 2 | x | − | 2418 5 | ( | 1 5 | − | x | ) | = | - | 6353 100 |
| Left side of the equation = | - | 787 2 | x | − | 2418 5 | × | 1 5 | + | 2418 5 | x |
| = | - | 787 2 | x | − | 2418 25 | + | 2418 5 | x |
| = | 901 10 | x | − | 2418 25 |
901 10 | x | − | 2418 25 | = | - | 6353 100 |
Transposition :
901 10 | x | = | - | 6353 100 | + | 2418 25 |
Combine the items on the right of the equation:
901 10 | x | = | 3319 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 3319 100 | ÷ | 901 10 |
| = | 3319 100 | × | 10 901 |
| = | 3319 10 | × | 1 901 |
We obtained :
| x | = | 3319 9010 |
Convert the result to decimal form :
| x | = | 0.368368 |
