| - | 5 | × | 981 100 | × | 23 10 | + | 3 | × | 981 100 | ( | 19 2 | x | − | 7 10 | ) | + | 3 5 | × | 981 100 | ( | 5 | x | − | 7 10 | ) | = | 0 |
| Left side of the equation = | - | 22563 200 | + | 2943 100 | ( | 19 2 | x | − | 7 10 | ) | + | 2943 500 | ( | 5 | x | − | 7 10 | ) |
| - | 22563 200 | + | 2943 100 | ( | 19 2 | x | − | 7 10 | ) | + | 2943 500 | ( | 5 | x | − | 7 10 | ) | = | 0 |
| Left side of the equation = | - | 22563 200 | + | 2943 100 | × | 19 2 | x | − | 2943 100 | × | 7 10 | + | 2943 500 | ( | 5 | x | − | 7 10 | ) |
| = | - | 22563 200 | + | 55917 200 | x | − | 20601 1000 | + | 2943 500 | ( | 5 | x | − | 7 10 | ) |
| = | - | 16677 125 | + | 55917 200 | x | + | 2943 500 | ( | 5 | x | − | 7 10 | ) |
| = | - | 16677 125 | + | 55917 200 | x | + | 2943 500 | × | 5 | x | − | 2943 500 | × | 7 10 |
| = | - | 16677 125 | + | 55917 200 | x | + | 2943 100 | x | − | 20601 5000 |
| = | - | 687681 5000 | + | 61803 200 | x |
| - | 687681 5000 | + | 61803 200 | x | = | 0 |
Transposition :
61803 200 | x | = | 0 | + | 687681 5000 |
Combine the items on the right of the equation:
61803 200 | x | = | 687681 5000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 687681 5000 | ÷ | 61803 200 |
| = | 687681 5000 | × | 200 61803 |
| = | 76409 25 | × | 1 6867 |
We obtained :
| x | = | 76409 171675 |
By reducing fraction, we can get:
| x | = | 701 1575 |
Convert the result to decimal form :
| x | = | 0.445079 |
