Work: Find the solution of equation x*99.975%-128.123*100.025% = 2/10 .
Question type: Equation
Solution:Original question:
| x | × | 3999 4000 | − | 128123 1000 | × | 4001 4000 | = | 2 | ÷ | 10 |
| Left side of the equation = | x | × | 3999 4000 | − | 512620123 4000000 |
3999 4000 | x | − | 512620123 4000000 | = | 2 | ÷ | 10 |
| Right side of the equation = | 1 5 |
3999 4000 | x | − | 512620123 4000000 | = | 1 5 |
Transposition :
3999 4000 | x | = | 1 5 | + | 512620123 4000000 |
Combine the items on the right of the equation:
3999 4000 | x | = | 513420123 4000000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 513420123 4000000 | ÷ | 3999 4000 |
| = | 513420123 4000000 | × | 4000 3999 |
| = | 171140041 1000 | × | 1 1333 |
We obtained :
| x | = | 171140041 1333000 |
Convert the result to decimal form :
| x | = | 128.387128 |
